We will introduce examples of surface treatments to prevent eye discharge that occurs during the extrusion molding of elastomers.
An elastomer is a type of synthetic resin that possesses elasticity and can change shape, being a polymer compound that has both rubber and plastic properties. This time, we received a consultation regarding the inability to produce stable products due to the occurrence of eye mucus in the mold during the extrusion molding of elastomers. ■ Background for Coating Adoption - Without surface treatment, the elastomer adhered to the mold to the extent that almost no products could be manufactured. - By adopting our Bi-Coat, we were able to prevent adhesion to a level that allowed for production. - It was found that after about a month of mass production, defects due to the adhesion of eye mucus occurred. ■ Effects of Surface Treatment Adoption - After adopting our 'MRS-102' and starting tests, eye mucus did occur, but it did not adhere to the mold and could be easily removed, which helped suppress the occurrence of defects, allowing for continuous use for six months. *For details on the adopted 'MRS-102', please refer to the materials or contact us.

basic information
◆MRS Coating◆ 【Series Features】 ■MRS-102 Maintains effectiveness even after cleaning with solvents. ■MRS-014 Preserves thinness like a blade and shapes such as corrugation. ■MRS-004 Heat resistance exceeding 200°C, comparable to fluororesin (release properties maintained even after 16 hours at 350°C). ■MRS-200 Can be heated with resin and rubber products at temperatures below 80°C. ■Release properties (non-stick) and excellent cleanability → The smooth surface makes it easy to wipe off dirt, and cleaning with solvents does not significantly change the release properties. *Based on our durability tests. *For more details, please refer to the materials or contact us.
