Metallic Stabilizers and Their Applications in PVC Foam Sheet Industry

In the world of chemical materials, metallic stabilizers play a key role in improving the properties and performance of many industrial products. One of the important applications of metallic stabilizers is in the production of PVC foam sheets. Each metallic stabilizer, such as calcium, zinc, barium, and magnesium, has specific functions, and their proper combination can have a significant impact on the final quality of PVC foam sheets.

In this article, we intend to take a closer look at the role and function of metallic stabilizers in the production of PVC foam sheets, and their use can affect thermal stability, lubrication, surface improvement, and increase the resistance of the final product. If you are active in the production of foam sheets, this article will be useful for you.

What is PVC Foam Sheet?

PVC foam sheet or rigid polyvinyl chloride sheet is a waterproof sheet made from lightweight and foamed PVC, which can be engraved, embossed, printed, colored, and coated according to user needs.

Structure of PVC Foam Sheet

PVC foam sheets are produced using the extrusion process, where raw materials are melted and then shaped in specific molds. Its internal structure consists of a foamed, lightweight, and porous core, while the outer surface is compact and resistant. This combination makes PVC foam sheets lightweight yet strong, resistant to moisture, chemicals, and impact.

Features of PVC Foam Sheet

✔️ High resistance to chemicals

✔️ Lightweight and flexible

✔️ Resistant to corrosion and cracking

✔️ Fire-resistant

✔️ Prevents deformation and maintains shape

✔️ Insect-resistant

✔️ Sound insulation

Why are Metallic Stabilizers Used in PVC Foam Sheets?

Due to their lightweight, moisture resistance, thermal and sound insulation properties, PVC foam sheets have a wide range of applications in the construction and interior decoration industries. Metallic stabilizers such as calcium and zinc act as heat stabilizers, preventing PVC degradation at high temperatures. Foam sheets absorb released hydrochloric acid during the thermal process, protecting PVC polymer chains and increasing thermal stability.

Other Applications of Metallic Stabilizers in PVC Foam Sheets

1. Lubrication: Metallic stabilizers reduce friction in the production process, improving material flow and reducing equipment wear. This feature increases production efficiency and reduces maintenance costs.

2. Mechanical Properties Improvement: Metallic stabilizers enhance particle dispersion and structural uniformity, strengthening the mechanical properties of PVC foam sheets, increasing their strength and durability.

3. Color Stability: These stabilizers help preserve the color and appearance of PVC foam sheets by preventing thermal degradation and oxidation, avoiding color changes.

4. Surface Quality and Mechanical Properties: Metallic stabilizers prevent material adhesion to equipment, creating a smooth and flawless surface in the final sheet. They also improve the strength and flexibility of foam sheets.

Comparison of Common Metallic Stabilizers Used in PVC Foam Sheets

Calcium Stabilizers

Role: Heat stabilizer and lubricant

Features: Calcium stabilizers are used as non-toxic heat stabilizers in PVC, preventing thermal degradation. This substance acts as an internal lubricant in the extrusion process, facilitating the production of foam sheets.

Application: Calcium stabilizers are mostly used in producing PVC foam sheets that require high heat resistance.

Zinc Stabilizers

Role: Heat stabilizer and mechanical properties enhancer

Features: Zinc stabilizers, in addition to heat stabilization, enhance the mechanical properties of PVC, preventing color changes and yellowing of foam sheets at high temperatures. This substance usually acts as a heat stabilizer system in combination with calcium stabilizers.

Application: Used in sheets that require high strength and appearance preservation, such as PVC foam sheets in automotive or construction industries.

Barium Stabilizers

Role: Heat stabilizer and surface improver

Features: Barium stabilizers are used as a high-performance heat stabilizer and have high resistance to UV radiation and temperature variations. This substance also helps improve the surface of foam sheets, protecting against surface cracking and environmental conditions.

Application: Barium stabilizers are mostly used in producing PVC foam sheets exposed to UV radiation or harsh environmental conditions, such as exterior building coatings and decorations.

Magnesium Stabilizers

Role: Internal lubricant and process improvement

Features: Magnesium stabilizers act as internal lubricants in the extrusion process, improving material flow and reducing friction.

Application: Mostly used in PVC foam sheets that require a faster and more efficient production process, such as foam sheets used in decorative panels and interior products.
