Products Features
- ACR processing aids can promote the melting of PVC, improve the surface finish, improve the elasticity of the melt, and enhance the elongation and strength of the melt.
- It is beneficial to cover the bubbles and prevent the collapse of the cells. The molecular weight and dosage of the foam regulator have a great influence on the density of the foam sheet: with the increase of the molecular weight, the melt strength of PVC increases, and the density of the foam sheet can be made lower, and the increase of the dosage of the regulator have the same effect. But this effect does not have a linear relationship. Continue to increase the molecular weight or increase the dosage, the effect on reducing the density is not very obvious, and the density will tend to be constant.
- Ultra-high molecular weight and super-strong melt strength endow products with lower density and uniform cell structure, especially suitable for PVC foamed thick board products.
- Give the product a uniform cell structure, high molecular weight and high melt strength, lower product density, and excellent processing performance.
- Good plasticizing ability, excellent melt fluidity, and good compatibility with PVC products, making the product more stable in size.
- Excellent plasticizing performance, endowing the product with excellent processing performance and excellent surface gloss.
Packaging and Storage
5Kg/bag. The product shall be kept clean during transportation, loading and unloading to prevent exposure to the sun, rain, high temperature and humidity, and to avoid damage to the package. It shall be stored in a cool, dry warehouse without direct sunlight and at a temperature lower than 40°C for two years. After two years, it can still be used after passing the performance inspection.
Frequently Asked Questions
What are the main specifications of KF-100 and KF-101?
KF-100 has an intrinsic viscosity of 16.00±0.75, while KF-101 has an intrinsic viscosity of 12.00±1.00. Both products are white powders with a 30 mesh residue of ≤2.0%, surface density of 0.45±0.10 g/cm³, and volatile matter of ≤1.50%.
How do ACR processing aids improve PVC processing?
ACR processing aids promote the melting of PVC, improve the surface finish, increase the elasticity of the melt, and enhance both the elongation and strength of the melt.
What is the effect of molecular weight on PVC foam sheet density?
As the molecular weight increases, the melt strength of PVC increases, allowing for a lower foam sheet density. However, continuing to increase molecular weight or dosage beyond a certain point will cause the density to tend to remain constant.
Which product is suitable for PVC foamed thick boards?
Products with ultra-high molecular weight and super-strong melt strength are especially suitable for PVC foamed thick board products, as they provide a lower density and a highly uniform cell structure.
What are the storage requirements for KF-100 and KF-101?
They must be stored in a cool, dry warehouse without direct sunlight, at a temperature lower than 40°C. Protect the packaging from exposure to sun, rain, high temperature, and humidity during transport.
What is the shelf life of these ACR processing aids?
The standard shelf life is two years under proper storage conditions. After two years, the products can still be used if they pass the necessary performance inspection.
