Properties of PVC impact modifier and its application
Apr 11 , 2023
PVC resin is a hard and brittle material with poor impact strength, generally only 3-5 kJ/m. The main reason for the need to improve the impact strength of unplasticized PVC is its sensitivity to notching. Besides, it is necessary to improve its low temperature impact resistance. By co-blending impact modifiers in PVC polymers, the toughness of PVC materials can be increased.These impact modifiers...

What is Plastic extrusion?
May 29 , 2023
Plastic extrusion is one of the most widely used manufacturing processes for plastic moulding as well as one of the most widespread manufacturing processes for thermoplastics. It is a method of forming a continuous profile with a constant cross-section by forcing a thermally melted polymer material through a head die under pressure by means of the extrusion of a screw or plunger. The extrusion pro...

Co-Extrusion Technology for Plastics Materials
Jul 05 , 2023
As the applications of plastic extrusion continue to expand, the requirements for the extrusion solutions become increasingly complicated. Many products designs require multiple functions in a simplified structure. However, each polymer material has its own characteristics and no single of them has the properties that can meet all desired needs. Therefore, the co-extrusion technology is created. C...
