AI Technical Summary
Technical Problem
The formation of biofilms on surfaces is a common issue, and there is a growing demand for resin compositions with enhanced biofilm resistance.
Method used
A biofilm-resistant resin composition is achieved by blending polyacetal resin with silicone of a specific molecular weight range (100,000 to 1,000,000) and optionally including polyolefin, with a silicone content of 0.1 to 3.0 parts by mass and polyolefin content of 0.1 to 3.0 parts by mass per 100 parts of polyacetal resin, resulting in a water contact angle of 71 to 90°.
Benefits of technology
The composition effectively prevents biofilm formation by making the surface water-repellent, thereby suppressing adhesion of microorganisms and dirt, demonstrating excellent biofilm resistance.
