December 12, 2001

Transparent blends can be obtained in either hard and rigid or soft and flexible versions, by modifier selection.
Asaflex™ neat and in blends can provide hardness and rigidity.
PP/Tuftec™ H1221 and other blends can provide the soft touch and feel of flexible PVC.

Transparencies of Asaflex™/PS and PP/Tuftec™ Blends

Asaflex™ – Excellent transparency, with inherent polymer hardness
Desired transparency may be obtained by matching the Asaflex™ and polystyrene refraction indices
or by controlling their blend morphology.

AFX835/SC*, 50/50	AFX835/GPPS, 50/50

Haze, 0.4% Tensile modulus, 1,180 MPa	Haze, 4.3% Tensile modulus, 1,420 MPa

*SC: Styrenic copolymer with refraction index near that of Asaflex™, from PS Japan Corp.

Tuftec™ H1221 – Excellent transparency with PVC-like softness
Nanometer-order dispersion in homo-polypropylene, enables high transparency.

h-PP/H1221, 80/20	h-PP/H1052, 80/20

Haze, 4.2% Young’s modulus Longitudinal: 340 MPa Transverse: 380 MPa	Haze, 17.8% Young’s modulus Longitudinal: 700 MPa Transverse: 550 MPa
