Vulcanized rubber powder in plastic products can not only reduce the cost of raw materials, but also improve the performance of plastics and the physical properties of the finished product, which is of great significance in the combined use of rubber and plastic. In actual production, the application effect of vulcanized rubber powder in different plastics is different. It can be used as a filler or as a modifier. Plastic products companies can choose the appropriate application method according to actual needs. The editor today shares with you the application characteristics of vulcanized rubber powder in different plastics.
1. Plastics that can be mixed with vulcanized rubber powder
Vulcanized rubber powder can be added to plastics (resins) such as polyethylene, polyvinyl chloride, polypropylene, polystyrene, polyurethane, phenolic resin, etc., to improve plastic properties and reduce raw material costs. The processing of waste tires and other waste rubber products into vulcanized rubber powder by normal temperature crushing, low temperature crushing, etc. is simple. The processing technology is simple. When used in the production of plastic products, it can save resources, reduce costs, and solve some waste rubber environmental pollution problems.
2. The role of vulcanized rubber powder in plastics
Different types of plastics have different processing technology and performance characteristics, and the effect of vulcanized rubber powder in them is different. In general, vulcanized rubber powder in polyethylene and polyvinyl chloride can significantly improve the impact resistance of 2LLYY1215 products. The use of vulcanized rubber powder in polypropylene can improve the toughness of polypropylene materials and increase impact strength. Vulcanized rubber powder is a commonly used impact modifier for polystyrene materials, which can be used to improve the toughness of materials through rubber-plastic blending. Adding vulcanized rubber powder to polyurethane can improve the wet friction factor and anti-slip performance of the material.
3. Usage of vulcanized rubber powder in plastics
The main function of vulcanized rubber powder in all kinds of plastics is to improve the impact resistance of materials. In actual production, the variety and dosage of vulcanized rubber powder used in different plastics are different. For example, mixing polypropylene with 30 mesh vulcanized rubber powder has better impact resistance than 60-80 mesh rubber powder. When polystyrene is mixed with 20%, 20 mesh vulcanized rubber powder, the impact resistance of the material is equivalent to that of medium-impact polystyrene.
When vulcanized rubber powder is used to fill and modify different plastics, different types of vulcanized rubber powder can be combined, such as polyvinyl chloride and nitrile rubber powder, after blending, the material has better impact resistance. In order to improve the mixing and modification effect of vulcanized rubber powder in plastics, you can use appropriate amount of compatibilizer in the blending materials. Later editors will have the opportunity to continue to discuss with you the different types of vulcanized rubber powder in a certain plastic application.
