High density A-C polyethylene wax can be used in PVC manufacturing process. It basically acts as an external lubricant while achieving many other benefits. The high-strength oxidized polyethylene wax is a very efficient external lubricant, which can accelerate the plasticization process and improve the metal peeling performance in the hard forming system. Its advantage is to improve the uniformity of the melt, thereby improving the dimensional stability of the profile and Productivity.
The high density oxidized polyethylene wax also improves weld line strength and metal release in conventional and hot runner systems in injection molding applications.
There are many commonly used AC waxes, such as Honeywell A-C 316A is one of them. A-C 316A is a low viscosity, high acid value oxidized polyethylene wax, often used to accelerate plasticization, with super strong metal stripping and excellent dispersion effect.
The main function of A-C 316A in PVC processing:
1. It imparts excellent metal peelability to calendering, extrusion, injection and blow molding equipment.
2. Generally, inappropriate dosage in PVC compound affects transparency, and the dosage of A-C316A in many transparent blow molding products reaches lphr and does not affect transparency.
3. A-C316A polyethylene has a relatively high softening point, so that PVC can maintain effective working viscosity under high temperature processing conditions.
4. Inhibit the frictional heat of PVC processing and improve the high temperature dynamic stability of PVC.
5. Improve the dispersion of impact agents and fillers in PVC, thereby increasing the impact strength.
6. Reduce the energy consumption of processing, especially in the process of PVC extrusion and molding.
7. Higher extrusion speed is allowed without affecting the appearance of the product.
8. Follow the recommended dosage without migration or precipitation.
9. Give the product an excellent surface gloss.
10. Since it does not contain metal ions, it can reduce the generation of fouling.
It can be said that this Honeywell A-C 316A has quite a lot of advantages. If there is any disadvantage, it is the price. Since it is an imported product, the price will inevitably be relatively high. However, there is now a domestic product that can perfectly replace the A-C 316A, that is the Reyler RL 916A!
RL 916A detailed parameters:
Acid value: 15-18mgKOH/g
Penetration: <0.5dmm
Dropping point: 140°C
Density: 0.98g/cc
Viscosity: 9000cps
RL-916A’s unique lubricating effect and plasticizing effect are not found in most lubricants, and the special product structure is a major advantage for reducing customers’ costs . It is often used in PVC products that require high plasticization, long-term continuous and stable production, and high requirements for mold release and appearance. Often added for PVC heat stabilizers, PVC foam products and CPVC products, etc.
Product application areas:
PVC wire and cable materials, TPE processing aids, PVC pipe fitting profiles, PVC foam board, PVC shrink film, decorative film, wax emulsion. If you are engaged in the production and processing of PVC and are looking for high-density oxidized polyethylene wax with high cost performance, you can try this Reiler RL 916A.
