    摘要： Geotechnical article, and process for making it, the article having coefficient of thermal expansion less than about 150 ppm/° C. at ambient; resistance to acidic media greater than polyamide 6 resin and/or resistance to basic media greater than PET resin; resistance to hydrocarbons greater than that of HDPE; creep modulus of at least 400 MPa at 25° C., at 20% of yield stress load for 60 minutes (ISO 899-1); and 1 percent secant flexural modulus at least 700 MPa at 25° C. (ASTM D790); the article including a composition including (a) from about 1 to about 95% by weight of the composition of at least one functional group containing polymer or oligomer; and (b) from about 5 to about 99% by weight of the composition of at least one engineering thermoplastic, and optionally containing a filler and optionally containing an unmodified polyolefin, ethylene copolymer or ethylene terpolymer.

    摘要： A geocell is disclosed that has high strength and stiffness, such that the geocell has a storage modulus of 500 MPa or greater at 23° C.; a storage modulus of 150 MPa or greater at 63° C. when measured in the machine direction using Dynamic Mechanical Analysis (DMA) at a frequency of 1 Hz; a tensile stress at 12% strain of 14.5 MPa or greater at 23° C.; a coefficient of thermal expansion of 120×10−6/° C. or less at 25° C.; and/or a long term design stress of 2.6 MPa or greater. The geocell is suitable for load support applications, especially for reinforcing base courses and/or subbases of roads, pavement, storage areas, and railways.
