Winona, Minn.-based compounder RTP Co. used the Plastics Encounter show at Antec to introduce a family of bondable thermoplastic elastomer materials, called the RTP 6042 Series, for use in combination with a wide range of rigid plastic substrates.
RTP has formulated standard grades to bond to polycarbonate, ABS, PC/ABS, PC/polymethyl methacrylate and thermoplastic polyurethane.
Products in the new RTP 6042 Series have a wider processing window than the RTP 6002 Series, which they replace, the company said. Additional improvements include superior bonding performance and more consistent mechanical properties.
“The critical element in any overmolding process is the chemical bond between the soft elastomeric material and the rigid substrate,” said Paul Killian, technical marketing manager for RTP's TPE Division.
The materials are especially good for rugged electronic devices that need excellent tensile and tear strength, plus abrasion resistance, according to Killian.
The 6042 Series materials are special alloys, but RTP is not releasing what type of TPEs are involved.
In other news, RTP has entered into a trademark agreement with Solvay Advanced Polymers LLC. Under the deal, RTP will compound and market pre-colored Radel R polyphenylsulfone and Udel polysulfone resins globally, using Solvay trademarks.
The agreement means customers that want small and mid-sized lots of pre-colored Radel R and Udel compounds can get them quickly from RTP.
