Abstract: An optically clear, high strength, high modulus, and high thermal conductivity polyethylene thin film may be formed from a crystallizable polymer and an additive configured to interact with the crystallizable polymer to facilitate crystallite alignment and, in some examples, create a higher crystalline content within the polyethylene thin film. The polyethylene thin film may be characterized by a bimodal molecular weight distribution where the molecular weight of the additive may be less than approximately 5% of the molecular weight of the crystallizable polymer. Example crystallizable polymers may include high molecular weight polyethylene, high density polyethylene, and ultra-high molecular weight polyethylene. Example additives may include low molecular weight polyethylene and polyethylene oligomers. The polyethylene thin film may be characterized by a Young's modulus of at least approximately 10 GPa, a tensile strength of at least approximately 0.7 GPa, and a thermal conductivity of at least approximately 5 W/mK.

Abstract: An NBR composition that includes, based on 100 parts by weight of NBR, 0.2 to 0.7 parts by weight, preferably 0.2 to 0.5 parts by weight, of stearic acid, and paraffin wax, which has the melting start temperature of 65° C., in an amount equal to 2 to 6 times the amount of said stearic acid, and preferably further zinc oxide and a UV resistant antioxidant. The NBR composition has improved ozone resistance using stearic acid and paraffin wax, which are generally compounded in NBR compositions, while neither affecting the material physical properties or product appearance, nor increasing the compounding amount of an ozone resistant antioxidant.

Abstract: A resin composition can includes a first isocyanurate component and a first bonding component bonded to the first isocyanurate component. The first bonding component can be configured to bond to a second bonding component that is bonded to a second isocyanurate component. The first bonding component can be configured to bond to the second bonding component based upon an application of an initiator to the resin composition. In this way, the first isocyanurate component can be coupled to the second isocyanurate component. The resin composition can be either in a pre-cured state in which the first isocyanurate component is not coupled to the second isocyanurate component or in a post-cured state in which at least a portion of the first isocyanurate component is coupled to at least a portion of the second isocyanurate component.
