UL Recognition and Flammability Ratings

For finished goods, frequently the UL Recognition of component materials can eliminate the need for some tests on the final product. This can significantly reduce both your cost and the time required for evaluation.

RTP Company offers support in material selection, design optimization, and plastic processing that can aid you in obtaining product certification from Underwriters Laboratories. Additionally, as a participant in UL’s Client Test Data Program we can expedite UL Recognition and issuance of “yellow cards” for our custom compounds.
