General Description:  

General Description : A linear isotactic polyolefin more properly called poly 4-methyl pentene-1 which is made by Ziegler-Natta type catalysis (see also General Information under Polyethylene - Low Density). Commercially available grades are copolymers. It is semi-crystalline, transparent and usually colourless (one common grade is slightly yellow), very light and - for a polyolefin - expensive. [Its density of 0.83g.cm 3 is very close to the theoretical minimum for thermoplastics]. Its properties are reasonably similar to those of other polyolefins, compared to which it is more brittle and more gas permeable. It has a higher melting point (240C) than most polyolefins and retains form stability up to temperatures close to this i.e. it softens more slowly with increasing temperature than is normal for thermoplastics. It has good release characteristics and good high frequency electrical and valuable acoustic/ultrasonic properties.

Applications include medical and laboratory apparatus, microwave components and cookware and electronic components.

Grades of TPX®

TPX® is available in a range of grades with different melt flow rates (MFR) covering injection moulding, extrusion, blow moulding and coating. The list shown below gives details of the main processing methods and the MFR for each grade:

DX845 MFR of 9 g/10 min - highly recommended for film extrusion, possible use for injection moulding, fibre extrusion and blow moulding.

RT31 & RT31XB MFR of 21 g/10 min - highly recommended for injection moulding, possible use for film and fibre extrusion.

MX002 MFR of 21 g/10 min - highly recommended for injection moulding, film and mandrel extrusion, possible use for fibre extrusion and blow moulding.

MX002O MFR of 21 g/10 min - highly recommended for injection moulding and film extrusion, possible use for mandrel and fibre extrusion, and blow moulding.

MX004 & MX004XB MFR of 25 g/10 min - highly recommended for injection moulding, film and mandrel extrusion, possible use for fibre extrusion and blow moulding.

RT18 & RT18XB MFR of 26 g/10 min - highly recommended for injection moulding, possible use for film and fibre extrusion.

DX231 & DX310 MFR of 100 g/10 min - highly recommended for paper coating and possible use for fibre extrusion.

DX350 MFR of 110 g/10 min - highly recommended for paper coating and possible use for fibre extrusion.

DX820 MFR of 180 g/10 min - highly recommended for paper coating and fibre extrusion.

RT31 & RT31XB: low odor grades RT18XB, RT31XB & MX004XB: blue tint grades
