RCH™ 500 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 (320°F to 338°F), is suited for deep-drawing and is both malleable and weldable. RCH™ 500 is commonly used for ankle foot orthoses, body jackets and upper limb orthoses.
