TPE provides optimum grip - even in wet conditions
02 February 2012
Kraiburg TPE has introduced thermoplastic elastomer (TPE) materials with optimum grip even in the presence of moisture for a range of consumer, industrial and medical applications. Wet Grip technology, offered under the THERMOLAST W trade name, boasts up to three times the coefficient of friction of conventional TPEs for both dry and wet applications with no negative impact on physical and rheological performance.
The Wet Grip technology, based on styrenic block copolymers, is permanent and incorporated throughout the matrix. It does not migrate to the surface and dissipate over time and has no negative impact on processability in multi-component injection moulding or extrusion processes. Kraiburg can adapt the technology to its broad portfolio of THERMOLAST branded elastomer compounds.
The technology can be used to eliminate the tackiness found in competing materials, which use tackifiers to achieve the wet grip, or it can be used along with tackifiers to improve friction performance. THERMOLAST W Wet Grip compounds can also be made to adhere to a range of engineering thermoplastics including acrylonitrile-butadiene-styrene (ABS) and polycarbonate (PC). They are available in 25-60 Shore A hardness and meet FDA approvals.
