Polycarbonate – Amorphous Thermoplastic
Polycarbonate (PC), first introduced in 1958, is an amorphous engineering thermoplastic with exceptionally high impact strength, transparency, high temperature resistance, and dimensional stability. It has a high surface gloss, and is available in many colors and color intensities. Additionally, it … Continue reading
Thermoplastics and Liquid Silicone Rubber (LSR)
Plastics are either organic or semi-organic materials that have (as their main attribute) a very large molecular weight. These very large molecules, or macromolecules, give them their distinct properties and material behavior, when compared to other materials used in manufacturing … Continue reading
The Chemistry That Makes LSR Such an Outstanding Material
Liquid Silicone Rubber (LSR) is part of the family of thermoset elastomers that have a backbone of alternating silicone and oxygen atoms with methyl (-CH3) or vinyl side groups (-CH=CH2). They offer properties not obtainable with today’s TPEs. The solidification … Continue reading
Why is LSR an Elastomer?
Plastics can be divided into uncross-linked thermoplastics and cross-linked thermosets. The first have intermolecular bonds between the molecule chains, but can move freely relative to their neighbors. They can be melted and solidified multiple times. In contrast, thermosets have “bridges” … Continue reading
