Core Performance Advantages

‌Ultra-low Processing Temperature & High Flowability‌
WSD CHEMICAL DG-700 PVC Resin can achieve full plasticization at a lower processing temperature, and its melt has excellent mold filling capacity. It can easily fill thin-wall, complex-groove and large-cavity injection molds, effectively reducing the injection pressure and equipment energy consumption.

High Transparency & Low Impurity Content‌
When used in combination with WSD CHEMICAL methyl tin heat stabilizer, it can obtain higher transparency and excellent initial color retention, avoiding yellowing and haze defects of transparent products.

Good Thermal Stability & Release Performance‌
Its narrow molecular weight distribution effectively reduces the residual internal stress of finished products, and it has a moderate demolding performance after curing. It can well match the high-speed cycle operation requirements of fully automatic injection molding machines, and greatly reduce the defective rate caused by sticking molds and uneven demolding.

Main Application Areas

PVC Injection Molding Parts‌: The preferred base material for producing high-precision thin-wall pipe fittings, transparent valve bodies, and electrical insulation injection parts, significantly improving the dimensional accuracy of finished products

High Transparency Products‌: Widely used in PVC transparent sheets, transparent containers, blister packaging and high-transparency hard decorative materials, with excellent surface gloss

Low-temperature Processing Compounding‌: Suitable for manufacturing low-melting-point PVC granules, printing calendered films and special low-viscosity modified materials

PVC or WPC foam board, foaming Wall panel
