MITSUBISHI CHEMICAL GROUP PRODUCT DATASHEET Borotron® HM015 shapes are made from high molecular weight polyethylene that is enhanced with 1.5% elemental boron. The boron enhancement makes this grade suitable for use in medical and nuclear shielding applications. The high hydrogen content of HMW-PE allows the material to absorb thermal neutrons, which are then absorbed by the added boron compound. For these reasons, Borotron® HM015 HMW-PE components are prevalent in nuclear and medical technology.

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...
