什么 SURECEL™ 466 ER Acrylic Processing Aid?
Acrylic additive which promotes a fine and well controlled PVC foam cell structure in free foam sheet and celuka profiles. In free foam sheet, the fine cell structure gives a very smooth and even surface which enhances the quality of laser jet printing techniques. In celuka profiles, the fine cell structure means fewer voids and faults within the cross section of the profile.
用途
- Free foam PVC sheet
- Thin sheet applications where surface quality for printing is critical
优势
- Promote fusion and increase gelation level
- Improve melt homogeneity
- Increase melt strength
- Increase melt elongation
- Increase melt elasticity
These key attributes result in:
- High melt expansion
- Low density PVC foam
- Reduced melt fracture and improved surface finish (smoother surface)
