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.

High strength and high modulus ultra-high molecular weight polyethylene fibers

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/mK.
