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.
用途
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)
利点
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)
