Specialty Compound Dissipates Static, Stays Tough


Rapistan Demag Corp. of Grand Rapids, MI develops conveyor systems for industrial environments, including airports, assembly plants and warehouses. The systems feature ball bearings with pressed-in and over-molded components.

The application requires a static dissipative material with ample elongation for a firm fit. An RTP 200 Series (nylon 6/6) specialty compound meets the dissipative and elongation requirements.

The material achieves a static decay of less than 2 seconds (based on Mil B-81705C). The material achieves an un-notched impact strength of up to 30 ft. lbs./in (1,620 J/m) at 1/8 in. thick and a flexural modulus of 380,000 psi (2,618 MPa).

The parts are molded under strict quality standards by Lakeshore Diversified Products in Spring Lake, MI. Lakeshore specializes in close tolerance and over-molded applications for industrial, automotive, consumer and other applications.

Depending on the specific application, the buildup of static electricity can cause mobility problems or even damage the materials in transit.
