LIM™ 8040

Chemical Family
Silicones

LIM™ 8040 liquid silicone rubber is a 2-component liquid injection molding material, which offers primerless adhesion to a wide range of substrates including metals and engineering plastics. Full bond strength is reached immediately after de-molding. This makes LIM 8040 the optimal choice for cost-efficient manufacturing of high numbers of articles in integrated processes such as multicomponent injection molding or insert-molding. If properly processed, parts made from LIM 8040 can meet the requirements for food contact. The requirements are determined in 21CFR FDA paragraph 177.2600 'Rubber articles intended for repeated use. It also has been successfully tested for USP class VI. Both applications usually require a postcure.Key Features and Benefits Primer-less adhesion to many substrates Maximum adhesion immediately after de-molding High temperature stability Excellent stability and flexibility at low temperatures Outstanding aging behavior and weathering resistance Good dielectric and mechanical properties Easy pigmentable due to translucent color Potential ApplicationsLIM 8040 is particularly suitable for the manufacturing of parts, where engineering plastics and elastomeric materials need to be combined in an overmolding or co-molding process such as: sealing elements, automotive connectors, membranes, vibration dampening elements.
