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?
The main difference 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. Other parameters like appearance, mesh residue, density, and volatile matter remain identical.
How do these processing aids benefit PVC processing?
They promote rapid PVC melting, improve surface finish, enhance melt elasticity, and increase both the elongation and overall melt strength during processing.
How does molecular weight affect the density of PVC foam sheets?
Higher molecular weight increases the melt strength of PVC, which helps prevent cell collapse and allows for a lower foam sheet density with a highly uniform cell structure.
Does increasing the dosage of the regulator indefinitely reduce the density?
No, the relationship is non-linear. Beyond a certain limit, continuing to increase either the molecular weight or the dosage will not significantly reduce the density further, and the density will tend to remain constant.
What are the recommended storage conditions for this product?
The product should be stored in a cool, dry warehouse away from direct sunlight, at a temperature below 40°C. It must also be protected from rain, high humidity, and direct sun exposure during transport.
What is the shelf life, and can the product be used after it expires?
The standard shelf life is two years. However, after the two-year period, the product can still be used safely provided that it passes a standard performance inspection.
