  • Patent number: 10392481
    Abstract: The present disclosure relates to a process for the preparation of high strength and high modulus polyethylene products/laminates consisting of steps such as providing a pre-dried, at least 50% disentangled ultra-high molecular weight polyethylene (UHMWPE) powder, feeding the UHMWPE powder having temperature ranging from ?15° C. to 50° C., at the nip of at least one pair of heated, polished counter rotating calendaring rollers, rotating at different roller speeds to obtain at least one pre-laminate and hot stretching the pre-laminate(s) at a pre-determined temperature and pre-determined stretching speed to obtain high strength laminates. The laminates provided by the present disclosure have tensile strength ranging between 0.5 GPa and 3.0 GPa and tensile modulus ranging between 40 GPa and 200 GPa.
    Type: Grant

  • Patent number: 10190236
    Abstract: The present disclosure relates to a compact polymer gel consisting of disentangled ultrahigh molecular weight polyethylene (dis-UHMWPE), at least one nucleator, at least one filler and at least one fluid medium. The present disclosure also provides a process for the preparation of the compact polymeric gel and fibers from the compact polymeric gel of both low and high denier values. The fibers prepared in accordance with the present process have tensile strength ranging from 2.5 to 13 GPa, tensile modulus ranging from 100 to 270 GPa.

  • Patent number: 10105880
    Abstract: The present disclosure relates to a process for preparing of high thermal conductivity and high heat capacity oriented ultrahigh molecular weight polyethylene (UHMWPE) product. The process includes feeding UHMWPE through rollers to obtain a pre-laminate which is further hot stretched to obtain the oriented UHMWPE product having high thermal conductivity and high heat capacity. The temperature of stretching is maintained below the melt temperature of the UHMWPE throughout the entire process. There is also provided a high thermal conductivity and high heat capacity oriented UHMWPE product prepared by the process of the present disclosure. The oriented UHMWPE product is characterized in the axial thermal conductivity in the range of 70 to 200 W/mK, transverse direction thermal conductivity in the range of 0.022 to 0.045 W/mK and heat capacity in the range of 6 to 25 MJ/m3K.
