What is SURECEL™ 445 Acrylic Processing Aid?
Acrylic additive which promotes a fine and well controlled foam cell structure in PVC 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.
Uses
- All types of rigid foam PVC extrusion applications
- Thin and thick sheet
- Free-foam and Celuka
- Profiles
- Foam-core pipe
- Foam sheet production for wide forgiving processing window
- Promoting flow uniformity across width of sheet die
- Rigid foam core luxury vinyl tile (LVT)
Benefits
- 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)
