HIM TM 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 Properties
Good 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 Properties
The 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 weathering
PS 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 treatment
Printing, 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.
Welding
Ultrasonic welding is normally used. High strengths can
be achieved with impulse welding. HF welding is not suitable.
Bonding
Only 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 & Safety
PS is physiologically safe.
