Engineers looking for components that will perform multiple functions in challenging conditions can download a guide and get free advice from a maker of rubber products.

Information in the 10-page "Rubber Polymer & Material Selection Guide" includes details on more than 15 categories of rubber polymers and materials and offers tips about hardness and temperature performance advantages and limitations. It also addresses rubber’s ability to bond to many substrates 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, extruded rubber products and precision rollers, prepared the guide.
