Pomona Electronics’ digital Multimeter Probe for diagnosing and troubleshooting circuitry is made with a two-step molding process. The first-step material for the inner mold is an RTP 100 Series polypropylene specialty compound with a UL flammability rating of V-2 at 1/32 in. This compound provides excellent moldability and non-corrosive characteristics.
The second-step overmold material is an RTP 2800 Series pre-colored thermoplastic elastomer incorporating Advanced Elastomer Systems’ Santoprene resin. The elastomer bonds well with polypropylene and gives the probe a soft-touch, non-slip grip.
RTP Company’s color specialists met the critical color matches for both materials. The polypropylene compound is precolored in red or black and paired with a light or dark gray elastomer. In addition, the company recently introduced connectors that feature RTP compounds in blue and yellow.
