  2. High-density polyethylene - Wikipedia

    en.wikipedia.org/wiki/High-density_polyethylene

    HDPE is known for its high strength-to-density ratio. [4] The density of HDPE ranges from 930 to 970 kg/m 3. [5] Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength (38 MPa versus 21 MPa) than LDPE.

    The contribution of the muscle to the specific heat of the body is approximately 47%, and the contribution of the fat and skin is approximately 24%. The specific heat of tissues range from ~0.7 kJ · kg−1 · °C−1 for tooth (enamel) to 4.2 kJ · kg−1 · °C−1 for eye (sclera). [13]

    Typical densities are 29 to 120 kg/m 3 (49 to 202 lb/cu yd) with the lower figure being common. [1] Densities as low as 14 kg/m 3 (24 lb/cu yd) can be produced. [2] Base polymer for EPE foams range from Low-density polyethylene (LDPE) to High-density polyethylene (HDPE). [2]
