Cheapest urethane rubber price is a series of elastomer materials containing more urethane groups on the polymer backbone. It is actually polyurethane rubber, referred to as Cheapest urethane rubber price or urethane rubber or polyurethane elastomer. In addition to urethane groups, polymer chains also contain ester groups, ether groups, urea groups, aryl groups, and fatty chains. It is usually formed by the reaction of oligomer polyols, polyisocyanates and chain extenders. Cheapest urethane rubber price varies according to the raw materials used and the ratio, reaction method and conditions, etc., forming different structures and varieties. So how much do you know about its classification knowledge? Let’s take a look at it with the editor below!
The traditional classification of polyurethane elastomers is based on processing methods, which are divided into cast polyurethane elastomers, mixed polyurethane elastomers and thermoplastic polyurethane elastomers. Due to different raw materials, synthesis and processing methods, and application purposes, reaction injection polyurethane elastomers (RIMPU) and solution-dispersed polyurethane elastomers have emerged. According to the formed form, it is divided into solid system and liquid system. It is also divided according to the chemical composition of raw materials. Generally, there are polyester or polyether, so there are polyether polyurethane elastomer and polyester polyurethane elastomer.
The above is a brief introduction to the classification of Cheapest urethane rubber price.
