Soft-Feel Grain Surface Treatment for Hard Plastic Mimics Sensation on Fingertips
- Sunday, 01 May 2011
This technology gives hard-surface plastics a soft and moist feel by imposing a “grain” or texturing onto the surface. It has application in automotive interiors, household utensils, electronics, mobile phones, and other locations where a hard plastic surface would benefit from feeling softer. The science is based on the study of the fingerprint. The more surface area of the fingertip that touches a surface, the more the brain interprets that sensation as “soft” and “moist.” The soft-feel grain surface treatment consists of a precise series of tiny bumps and larger bumps designed to increase the area of the surface in contact with the fingertip.
This soft-feel grain surface treatment is formed into the surface, not painted on, thus reducing the number of production steps and eliminating the possibility of peeling or wearing away during the expected life of the product. The surface texturing technology avoids the entire painting-curing-drying process, and the non-painted soft-feel surface is not subject to the cracking, peeling, and wear of a painted surface.
