Comprehensive Introduction to PVC E7044
Product Name: PVC E7044
Product Type: Polyvinyl Chloride (Emulsion Homopolymer)
Manufacturer: Arvand Petrochemical Company
General Description
PVC E7044 is an emulsion-based polyvinyl chloride homopolymer (Paste PVC) designed for the production of low-viscosity pastes with nearly Newtonian flow behavior. These specific rheological characteristics make it ideal for a wide range of applications, especially in coating, molding, and the production of soft and uniform foams.
This grade is engineered to deliver smooth, stable, and efficient performance in various industrial processes, including casting, dipping, rotational molding, and fiber coating.
Technical and Performance Features of PVC E7044
1. Suitable Rheology
Low viscosity (less than 7 Pa·s after 1 hour), facilitating casting and paste preparation.
Its Newtonian flow ensures uniform surface distribution and reduces defects during coating.
2. High Foam Production Quality
Capable of producing chemical foams with a uniform and closed-cell structure
Excellent performance across a wide range of oven curing temperatures
Compatible with soap- or silicone-based foam stabilizers
3. Physical and Chemical Stability
Resistant to moisture absorption
Thermal stability for over 20 minutes at 180°C
Extremely low residual vinyl chloride monomer (VCM) content – less than 1 ppm
4. Wide Compatibility with Industrial Processes
Suitable for rotational molding
Applicable in dipping processes for manufacturing gloves and flexible parts
Ideal for glass fiber coating, especially in advanced industrial applications
