New grade PVC-S-8059 U is a special product with a narrow particle size distribution, high porosity (over 30%) and bulk density of about 0.5 g/cm3. It can be used alone or blended by known hot and cold mixing methods with PVC with a lower K-value to make compositions for further processing on the conventional equipment by extrusion, calendering and injection molding. The materials prepared using PVC-S-8059U as a polymer base have high physical and mechanical properties and are resistant to low (minus 50-60°С) and high temperatures.

Technical Details & Test Data
- SPECIAL PROPERTIES
Polyvinyl chloride is a combustible substance. Flash point of air-suspended particles is 624°C, aerogel self-ignition point is 486°C. Polyvinyl chloride does not burn and is not explosive on contact with water, acids, alkalis and aerial oxygen.
Packaging & Availability
- Packaging Type
- PACKAGING AND TRANSPORTATION
The suspension polyvinyl chloride should be packed into three- or six-ply paper bags, in special big bags made of polypropylene fabric. PVC-S can be transported by rail and by road. Polyvinyl chloride in bags, transport packs and special big bags should be stored indoors at least one meter away from heating devices at a temperature below 35°С and maximum relative humidity of 75%. It can be stored under a shed in storage areas protected from direct sunlight and precipitation.
