Exploration Of LPBd In HCR silicone

Silicone has always been a superior polymer for heat stability. Its ability to withstand higher temperatures than any other polymer has prompted its growth in high heat applications, such as automotive. Many high temperature applications are also exposed to chemicals. Many VMQ silicones alone cannot meet the chemical resistance specification on these applications. Therefore, specialty fluoropolymers are used in these applications where high temperature and chemical resistance are needed.

Dimensional Change Resulting From Swell And Drawdown Of Extruded Polymers

Understanding and predicting how extruded profile dimensions change along an extrusion line contribute significantly to the design of shaping dies and the effectiveness of dimensional control. Upon exiting the extrusion die, the dimensions of nonsymmetric profiles change non-uniformly along the line due to swell and drawdown.
