Engineers looking for components that will perform multiple functions in challenging conditions now have a guide, downloadable for free from a maker of rubber products. Information in the 10-page “Rubber Polymer & Material Selection Guide” includes technical details on more than 15 categories of rubber polymers and materials.

Material specifications include hardness, temperature ranges performance advantages and limitations. Also addressed is rubber’s ability to bond to many substrates, eliminate parts and lower assembly costs. The guide allows users to create a short list of potential polymers for their applications.

Robinson Rubber Products, Minneapolis, a manufacturer of custom-molded rubber products, prepared the guide. To download it, visit or send an e-mail to
