PVC E66 is a finely particulated emulsion homopolymer specifically engineered for creating medium-viscosity plastisols. This product is designed to deliver outstanding performance in applications requiring excellent foaming characteristics and shelf stability.
 
Product Description
Type: Emulsion Homopolymer
Characteristics: PVC E66 produces plastisols with slightly pseudoplastic rheology, ideal for applications requiring good flow under stress but stability under low shear conditions. It is especially effective in producing chemically blown foams, enhancing both the aesthetic and functional qualities of the products.
Foaming Characteristics: Exhibits exceptional performance in creating foams, particularly suited for screen printing and hot embossing processes used in wall covering manufacturing.
 
Key Applications
Leather Foam: Used in the production of foam leather for various consumer goods, providing comfort and enhanced aesthetics.
Wall Covering: Ideal for wall coverings where foam characteristics contribute to insulation and texture.
Cushion Floor: Applied in cushion flooring solutions where durability and comfort are required.
 
Typical Properties
K-Value: 46-44 (ISO 1628/2), indicating the polymer’s degree of polymerization and influencing the material’s mechanical properties and processing characteristics.
Sieve Analysis: ≥63µ is ≥5.1% (ISO 565), ensuring that a significant proportion of the particles are above the specified micron size, contributing to the uniformity and stability of the plastisol.
Volatile Matter: ≥3.0% (ISO 1269), quantifying the amount of material that can evaporate at elevated temperatures, which is critical for processing stability.
Methanol Extract: ≥2% (ISO 6427), providing insight into the amount of polymer soluble in methanol, which can affect the resistance of the final product to solvents.
Residual VCM: ≤5 ppm (ISO 6401), a critical safety measure indicating minimal vinyl chloride monomer left in the product, enhancing its safety profile.
Thermostability: ≤51 minutes (Vinnolit THMA 180), reflecting how long the material can withstand thermal processing without significant degradation.
Paste Viscosity: ≥7 (ISO 3219), measuring the viscosity of the PVC paste which affects its application and performance in end-use products.
 
Summary
PVC E66 is tailored for specialized applications where medium viscosity, excellent foaming properties, and high stability are required. Its formulation allows for use in high-end decorative and functional applications such as leather foams, wall coverings, and cushioned flooring. The combination of fine particle size and specific chemical properties ensures that PVC E66 meets rigorous industry standards, making it a valuable product for manufacturers in various sectors looking for reliable and high-quality PVC solutions.
