Introduction

Polyvinyl chloride (PVC) foam board is becoming a popular choice for residential and commercial application. PVC foam board is made from polymerized vinyl chloride which contains chlorine and carbon atoms. Chlorine atoms make the PVC or poly vinyl chloride flame resistant whereas carbon atoms give strength to the material.

When making PVC foam boards, two types of raw materials are mainly used. One of them is rigid PVC resin, which gives strength and rigidity to the PVC Foam Board. The other ingredient used in pvc foam boards for home depot are additives such as fillers, processing aids and impact modifiers that provide desired properties to the pvc panels & sheets like low flammability and high impact resistance etc… In this post we will discuss these ingredients used in pvc foam board in detail and their effect on properties of pvc sheets & panels

Polyvinyl chloride was commercially used since mid-19th century.

It is an important chemical for the manufacture of many commercial and household products. It is also a component of flexible vinyl sheets, used in construction and automotive applications.

According to the American Chemistry Council, “PVC is one of the most widely used materials in the world.”

What is PVC foam board?

PVC foam board is a type of foam board that is made of polyvinyl chloride (PVC). It can be manufactured using a variety of chemicals and ingredients. You will find that there are two main types: extruded and expanded.

Extruded foam boards are manufactured by mixing PVC with a blowing agent such as carbon dioxide (CO2), nitrogen, or air. The mixture is then forced through an extrusion die to create the final product. This type of board has higher density than expanded PVC, but it also has less flexibility and durability than the expanded version.

Expanded PVC is created by heating up the mixture until it expands into its finished shape through an expansion process known as foaming or blowing agents inside the heated material expand rapidly due to increased pressure which results in cells being formed within each layer or sheet that make up what we call “foam”. The resulting material resembles Styrofoam®, which makes sense considering its chemical makeup includes polystyrene beads dispersed throughout layers of PVC film sheets sandwiched together by heat pressing them together into one solid sheet!

Foaming agent in pvc foam board

Foaming agent is a chemical that is added to the polymers to make them expand during foaming process. Foam is the substance created when a gas or other materials are mixed with polymer liquids, which causes rapid expansion of the material.

The foaming agent added in PVC foam board can be natural or synthetic, depending on your preference and budget. If you do not want to use chemicals that are harmful to our environment as well as yourself, it’s best to opt for natural alternatives such as soybean oil or coconut oil rather than petroleum-based chemicals like Stoddard solvent (which releases toxic vapors).

Other chemical components of PVC foam board

Other chemical components of PVC foam board, in addition to the plasticizer and stabilizer, include non-toxic flame retardants. These are chemicals added to the polymer before processing to reduce flammability. These chemicals help prevent flames from passing through the material during a fire. They work by creating air pockets within the foam that act as an insulator and slow down oxygen flow into a burning area (Figure 2).

The European Union has banned some of these substances, including brominated compounds like brominated diphenyl ether (BDE) or bromochlorodifluoromethane (BCF). However, U.S.-made products continue to be manufactured with BDE or BCF as well as other additives under new names such as: pentabromodiphenylether (PBDPE), tetrabromobisphenol A diphenylamine epoxide resin (TBBA), tris(2-chloroethyl) phosphate (TCEP), and hexabromocyclododecane hydrobromide (HBCDD).

Chemical flame retardants of pvc foam board

A flame retardant is needed to be added to the foam board in order to meet the flammability requirements for building codes. The most common boric acid flame retardant is used in PVC foam board and can be found in many other products such as vinyl flooring, plastic housing, and car interiors.

Boric acid is a non-toxic, inorganic compound that is found naturally in soil and water sources. It’s also used by some people as a pesticide or insecticide on their land. However, long term exposure to boric acid can cause various health effects including damage to red blood cells (hemolysis), cataracts and neurological problems like depression or irritability. It’s best not to eat foods with high amounts of boric acid because they may contain too much of this chemical that could cause side effects over time if ingested regularly over time

Properties of PVC Foam Board

• Density

PVC foam board is a closed-cell foam. It has a density of about 1.2 pounds per cubic foot or about 0.8 grams/cubic centimeter. This means that it is light in weight and easy to handle, yet strong enough for most applications such as construction projects where you need to make walls for your garage or shed, signboards etc. You can also use it in workshops and other areas where light-weight materials are needed to hold things together without incurring additional costs due to heavy material weights like concrete or metal frames being used as supports instead of just using PVC foam boards alone.* Flexibility & Rigidity

The flexibility level of PVC Foam Board lies between that of rigid insulation materials like foamed polyurethane board (FPB) and flexible ones like extruded polystyrene boards (XPS). The rigidity index depends on density – the higher the density, higher will be its rigidity index.* Non-toxic nature

1) Effect of foaming agent on mechanical properties of pvc foam board

There is a chemical called a foaming agent that is used to make PVC foam board and other types of foam. The use of this chemical in the manufacturing process affects the mechanical properties of the resulting material, so it’s important to know how to identify PVC foam boards made with different types of foams.

2) Thermal stability and fire resistance of pvc foam board

PVC foam boards are not as good in terms of fire resistance as some other insulation materials. Foam plastics are combustible and can ignite at temperatures as low as 400°C. They burn slowly, releasing toxic gases and smoke. PVC Foam board has a flame spread index (ASTM D2863) of 80-100 and is therefore unsuitable for use in buildings above ground such as schools and hospitals or around highly inflammable places such as oil tankers etc. However, there are some applications where PVC foam boards can be used safely if adequate measures are taken to control the risk of fire spread e.g., by using ventilation systems through windows or roofing materials that will provide sufficient air supply to prevent the buildup of harmful levels of carbon monoxide gas generated during combustion process due to incomplete burning process by fire source heat source ignition source (flame spread index).

PVC foam is an inexpensive material that makes great packaging and insulation. It’s also strong, durable and lightweight. But, despite its many benefits, it has a few drawbacks as well. If you’re considering using pvc foam board in your home or business, it’s important to understand all the aspects of this product so that you can determine whether it’s right for you.

What Is PVC Foam Board?

PVC foam board is a type of thermoplastic produced by combining polyvinyl chloride (PVC) with foaming agents such as sodium bicarbonate or sodium carbonate (baking soda). The resulting material can be pressed into boards which are then cut into sheets or molded into custom shapes depending on how they are manufactured.

The most common type of PVC used in this process is low-density polyethylene (LDPE), but high-density polyethylene (HDPE) can also be used if required by the manufacturer due to other factors like availability versus cost per cubic foot cost etc., although they will not perform identically since LDPE has lower density than HDPE due its molecular structure which makes them different types of plastics even though both have similar chemical compositions when comparing their molecular structures at an atomic level..

Conclusion

So, these are some of the most common types of PVC foam boards you can find in the market. You can use them for a wide range of applications starting from creating exhibition stands to making wall panels. All you need is to choose the right type of board depending on your needs and requirements.
