Product 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 (FAQ)
What is the difference between KF-100 and KF-101 processing aids?
The primary difference between KF-100 and KF-101 is their intrinsic viscosity. KF-100 has an intrinsic viscosity of 16.00±0.75, whereas KF-101 has an intrinsic viscosity of 12.00±1.00. Both feature the same physical state, surface density, and volatile matter standards.
How do ACR processing aids improve PVC processing?
ACR processing aids promote faster melting of PVC, enhance melt elasticity, elongation, and strength, and improve the final surface finish of the PVC products.
Why are these processing aids suitable for PVC foamed thick boards?
Their ultra-high molecular weight and super-strong melt strength provide a uniform cell structure and lower density, which is highly beneficial for thick foamed PVC board applications.
What are the packaging specifications for KF-100 and KF-101?
Both products are packaged in 5Kg bags, designed to be clean and easy to handle during transport and storage.
What is the shelf life and proper storage condition?
The shelf life is two years when stored in a cool, dry warehouse below 40°C, away from direct sunlight, moisture, and rain. The product may still be used after two years if it passes a standard performance inspection.
