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 is the key difference between KF-100 and KF-101?
The primary difference lies in 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.
How do ACR processing aids improve PVC products?
They promote the melting of PVC, improve the surface finish, increase the elasticity of the melt, and enhance both the elongation and overall strength of the melt.
How does the molecular weight affect PVC foam sheet density?
As molecular weight increases, the melt strength of PVC increases, which allows for a lower foam sheet density. However, this effect is non-linear and eventually stabilizes.
What are the packaging options for these processing aids?
The products are standardly supplied in 5Kg bags, and they must be kept clean and undamaged during transport and handling.
What are the recommended storage conditions?
They should be stored in a cool, dry warehouse away from direct sunlight, rain, high humidity, and at a temperature strictly below 40°C.
Can the product be used after its two-year shelf life?
Yes, the product can still be used after the two-year storage period, provided it successfully passes a performance inspection.
