Semi-Crystalline – HTP

High Performance Engineering (Semi-Crystalline)
High Temperature Plastics

LCP – Liquid Crystal Polymer – LCPs are highly crystalline, inherently flame retardant, thermotropic (melt-orienting) thermoplastics. LCPs typically have outstanding mechanical properties at high temperatures, excellent chemical resistance, inherent flame retardance and good weatherability.

PAR – Polyarylate – A type of aromatic polyester noted for their strength, toughness, chemical resistance, and high melting points. When exposed to UV light, this material undergoes a molecular rearrangement resulting in the formation of a protective layer that essentially serves as a UV stabilizer

PARA – Polyaryl Amide – semi-aromatic, semi-crystalline polyamide base resin is compounded with glass fibre, carbon fibre, mineral and/or advanced fillers. These grades exhibit very high strength and rigidity, outstanding surface gloss, and excellent creep resistance.

PPA – Polyphthal Amide – outperform standard polyamides with higher strength and stiffness at elevated temperatures, better retention of properties in humid environments, and greater resistance to a broader range of chemicals.

PPS – Polyphenylene Sulfide – An exceptional degree of inherent thermal stability, dimensional stability, chemical resistance, and flame resistance, combined with excellent mechanical and electrical properties.

PA11 – Polyamide 11 – semi-crystalline aliphatic polyamide with a very high chemical resistance. It has relatively little amide groups in the chain compared to the most common nylons ( PA6 and PA66), therefore, the moisture absorption is low. This means that the mechanical properties and dimensions are not influenced much by the environment it is used in. PA11 is produced from a renewable resource: castor oil. It can be used at a wide temperature range, and remains ductile down to very low temperatures (-40 °C or even lower).

PA12 – Polyamide 12 – a semi-crystalline aliphatic polyamide with a low moisture uptake and very high chemical resistance. Just as PA11 it has much less amide groups than PA6 and PA66, which causes the Young´s Modulus to be lower, but it is much less affected by moisture from the environment. PA12 is very ductile, even at low temperatures. Other characteristics are the low coefficient of friction and high wear resistance.
