STRENE HIPS (Hi Impact Polystyrene Sheets) :These contain a small amount of rubber which improves the materials impact and high temperature resistance. Products manufactured from this material can have excellent surface finish ideally suited to printing.
Hip Sheets are available in thickness ranging from 0.5 mm to 6 mm in various colors like natural, ice blue and light beige. Uses & Applications :. Used in thermoformed parts for refrigerator lining,
sanitary ware, disposable containers etc.
. Television Cabinets, Appliances, Toys, Compact Disc "Jewel Cases" & Audio Cassettes Cases. . Indoor and outdoor Advertising such as display racks, Display Boards, Sign ages, Glow signs. . Food Packaging: Carry away burger Boxes Biscuit & Cake trays etc. . General Packaging: Printer Cartage box, Tools Packaging etc. . Insulation Purposes. . Thermal Properties Polystyrene can be used down to temperatures just below this range (70°C) PS can also be used at low temperatures down to 70°C. Electrical PropertiesGood electrical resistance values that are virtually independent
of the moisture content. PS shows a marked tendency to form electrostatic charges
- the old style PS rulers can be used to demonstrate static electricity with
small pieces of paper, the classic demonstration.
Optical PropertiesThe transparent types of standard polystyrene have a light transmission
of about 90 in the visible range. Absorption increases considerably in the UV
range. The refractive index is 1.59.
Resistance to weatheringPS is not recommended for long-term use in the open air as it
is degraded by UV rays. This is reflected in yellowing and loss of surface gloss
and by a decrease in mechanical strength. Darker formulations perform better
than pale or transparent types.
Surface treatmentPrinting, lacquering and hot stamping are all possible. PS can
be given a mirror finish with a metallic gloss by high-vacuum metallizing with
a clear lacquer applied for protection.
WeldingUltrasonic welding is normally used. High strengths can be achieved
with impulse welding. HF welding is not suitable.
BondingOnly parts of the same type can be bonded together. Solvent adhensives
such as toluene or methylene chloride are normally used. Impact adhensives are
used for bonding with different materials.
Health & SafetyPS is physiologically safe. |
