สารช่วยในการขึ้นรูป (Processing aid) เป็นสารที่ช่วยให้การหลอมตัว
ขึ้นรูปของพีวีซีง่ายขึ้น เพิ่ม Melt strength ของพีวีซีที่หลอมทำให้ขึ้นรูปได้ง่ายขึ้น
นอกจากนี้ยังช่วยลดการเกิด Plate out และช่วยให้ผิวชิ้นงานสวยงาม
ตัวอย่างของ สารช่วยในการขึ้นรูปที่นิยมใช้กัน เช่นกลุ่ม Acrylic polymer
Processing aids products are high
molecular weight polymers developed by our company using advanced
polymerization technology and drying techniques. These products can improve PVC
gelation, fusion fluidity and processing performance and are broadly used in
PVC profiles, sheets, pipes, pipe fittings and foam products.
Acrylic process aids have been
widely used for decades in the production of both rigid and flexible PVC
materials. Their advantages are well-known and are briefly reviewed in this
paper. Excessive use of process aids or selection of the wrong molecular
weights may, however, lead to undesirable behavior ultimately resulting in
defects in PVC materials. These limitations are discussed in detail and
explained on the basis of general polymer science considerations. Some criteria
to optimize the proper selection of the level and nature of the process aids in
PVC formulations are given in relation to the final applications, such as
films, window and foam profiles, pipes, and so on.
Processing aid PA-551T is a medium
molecular weight acrylic polymer resin. This processing aid contributes greatly
to rapid growth of market for rigid or soft PVC compounds such as calendered
sheet, extrusion profiles, blow molding and rigid foam. It develops
acceleration fusion rate, increasing productivity and decreasing processing
temperature. Better dispersion of additives into PVC, more homogenous melting
of PVC. Give excellent hot strength, cohesion, rolling bank and well-knit
edges. Provides smooth glossy surfaces, free of pinholes and air streaks.
Self-lubricating, helps eliminate plate out, improve impact efficiency
Processing aid PA-530 is a high
molecular weight acrylic polymer resin. This Processing Aid
contributes greatly to rapid
growth of markets for rigid or soft PVC compounds such as
calendered sheet, extrusion
profiles, blow molding and rigid foam extrusion.
