PVC Paste Resin TPH-31 For Keychain Toy Trojan
Description Of PVC Paste Resin TPH-31:
The lotion polymerization formula mainly includes VCM, water, water-soluble initiator and emulsifier. Lotion polymerization has strict requirements on agitation. The initiation is carried out in the water phase. The commonly used initiator is water-soluble persulfate. Generally, the particle size of lotion obtained by emulsion polymerization is less than 0.2 μ m. In order to increase the particle size of the emulsion, the lotion seed polymerization method was developed to increase the particle size of the emulsion to 1.0 μ About m. In lotion polymerization, if there is generated high polymer latex, control the material ratio and conditions. In principle, VCM will only polymerize on the generated latex particles, and no new particles will be formed; The generated polymer latex is like crystal seed, so it is called "lotion seed polymerization". But only a reasonable particle size is not enough. It is necessary to have an appropriate particle size distribution in order to obtain PVC paste resin with excellent performance. Emulsifier is very important in lotion polymerization. The amount used determines the number of initiator particles and plays a major role in the final size of latex particles. Especially when producing seeds, using high initiation rate and low concentration emulsifiers can narrow the particle size distribution of latex.
