Product Detail

PVC Impact Modifier For Pvc Pipe


Product features
The PVC modifier has excellent modification effect with less dosage, which conforms to EU ROHS Directive, eco-friendly and without secondary pollution. The PVC impact modifier has good compatibility and doesn't precipitate, which is the preferred choice of environmental protection efficient modifier in PVC industry.

To adopt the modifier of acrylic modification, fundamentally changed the current CPE modified method, which is in line with international advanced technology. It can decrease the rest chlorine of CPE products erode screw and other equipments.

The impact modifier for PVC has good modification effect, excellent processing performance, make the products appearance gloss improved greatly, with moderate hardness and the synergistic effect of thermal stability enhanced. This modifier also have functions of antioxidant and light stability, which can improve the weather resistance and heat resistance of various PVC products.

Usage advice:
PVC mixing temperature:
Lead based stabilizer      120-125 centigrade
Calcium zinc stabilizer     115-120 centigrade

Processing temperature (centigrade):
First area  second area  third area  fourth area fifth area the die orifice temperature
180-185     180-185       175          175       170           188-195

As per different molds, draggers and equipments, the manufacturers should base on their own requirements to adjust the lubricant dosage and processing temperature accordingly to achieve the best plasticizing effect.
 
Packing and transportation:
The products should be stored in dry and cool place with air ventilation, and pay attention to moisture proof.
The products packed in plastic woven bag lined with PE bag, 25kg net weight per bag.
