MITSUBISHI CHEMICAL . GROUP PRODUCT DATASHEET RCH® 500 HMW-PEHigh Molecular Weight Polyethylene RCH® 500 High Molecular Weight HMW-PE is a highly versatile, high-molecular weight plastic that is ideal for many orthotic applications. It has a forming temperature between +160°C to 170°C , is suited for deep-drawing and is both malleable and weldable. RCH® 500 is commonly used for ankle foot orthoses, body jackets and upper limborthoses. Test methods Tensile strength Electric strength Note: 1 g/cm3 = 1,000 kg/m3 ; 1 MPa = 1 N/mm2 ; 1 kV/mm = 1 MV/m NYP: there is no yield point This table, mainly to be used for comparison purposes, is a valuable help in the choice of a material. The data listed here fall within the normal range of product properties of dry material. However, they are not guaranteed and they should not be used to establish material specification limits nor used alone as the basis of design. See the remaining notes on the next page.

Notes, see datasheet on page 1 1. The figures given for these properties are for the most part derived from raw material supplier data and other publications. 2. Values for this property are only given here for amorphous materials and for materials that do not show a melting temperature (PBI & PI). 3. Temperature resistance over a period of min. 20,000 hours. After this period of time, there is a decrease in tensile strength – measured at 23 °C – of about 50 % as compared with the original value. The temperature value given here is thus based on the thermal-oxidative degradation which takes place...
