According to the molecular structure of synthetic resin, plastic raw materials mainly include thermoplastic and thermosetting plastics. For thermoplastic plastics, plastics that are plastically heated repeatedly: mainly PE/PP/PVC/PS/ABS/PMMA/POM/PC/PA And other common raw materials. Thermosetting plastics mainly refer to plastics made from heat-hardened synthetic resin, like some phenolic plastics and amino plastics, not commonly used. According to the application range, there are general plastics such as [1]PE/PP/PVC/PS, engineering plastics such as ABS/POM/PC/PA, etc. There are also some special plastics such as […]

The main component of plastic toys is resin. Raw materials for plastic toys: Infiltrated into various auxiliary materials or additives by polymer synthetic resin (polymer) as […]

Is plastic toys safe? Learn how to choose a plastic toy: 1. Look at the security label Regular toy manufacturers will attach safety labels to the packaging of the toys and have complete information. Including: applicable age, quality system, materials used, etc., recoverable conditions, etc. 2. Look at the size Includes external and internal dimensions. Toys can’t have detachable small parts. If they are put off their mouths and put them in their mouths, they may cause dangers such as […]

First, in the selection of materials to consider: 1. Physical and mechanical properties of plastics such as strength, rigidity, toughness, elasticity, water absorption and sensitivity to stress; 2, plastic molding process, such as fluidity, crystallization rate, sensitivity to molding temperature, pressure, etc.; 3. The shrinkage of plastic products after molding and the difference in shrinkage ratios. Second, in the shape of the product: can meet the requirements of use, is conducive to filling, exhausting, feeding, and can be adapted to […]
