TH19409C3 - Soft rubber doll mix formula and production process - Google Patents

Abstract

A summary of the invention which will appear on the advertisement page ReadFile:Page 1 of 1 Page Summary of the invention of the soft rubber doll formulation and its manufacturing process consisting of para rubber, starch, glycerin, surfactant, catalyst. The reaction has three production steps: 1. Preparation of rubber compounds 2. Preparation of rubber compounds 3. Extrusion into molds of doll shape according to the design process for preparing soft rubber dolls that can be broken This can be achieved by using natural rubber as the main component in combination with a rubber softener and the addition of a catalyst catalyst to give the prepared rubber dolls good softness and flexibility as well as resistance. Good strength makes it difficult to use for a long time when the workpiece is difficult to tear.
