These are used to increase the life of chains & it helps in reducing wear to the sliding part. As it has a very low co-efficient of friction chains slides easily without much effort or initial torques at both the pulley ends above all it is best suited for bottling plants as it reduces noise level & outperforms in increasing the chain life without any greasing.

As UHMWPE has an excellent slide ability , highly abrasion resistant ,approved material for Food contact grade it is an ideal choice by the machine manufacturer  & the end user to reduce frequent replacement of parts as well as to reduce the noise level in plants.

Pharmaceutical inspection unit (star-wheel, infeedscrew, various guides) In packaging and filling plants, the food industry, transport, conveying and storage technology etc., wear-, impact- and chemical-resistant components (e.g. profiles for chain/belt drives, curved guides, chain and belt deflecting and tensioning devices, bearing bushes, rail track disks and impact-absorbing elements etc.) can provide a trouble-free operation with low maintenance.

PEEK is one of the first of the 'new generation' of engineering thermoplastics used for extreme conditions The poly ether ether ketones have repeating monomers of two ether and ketone groups and PEEK is one of the highest rated thermoplastic materials in terms of heat resistance. The useful properties of the material are retained at temperatures as high as 315oC.

The materials have excellent -

• Good chemical resistance
• High strength and good resistance to burning
• Highly wear resistance
• The co-efficient of friction and wear rate are low over a wide temperature range.
• The thermal oxidative stability of PEEK is excellent and the material has a UL rated continuous operating temperature of around 250oC.
• It is toughest amongst all POLYMERS but equally the high cost of these materials makes applications limited to those where the properties are very necessary.

Some of its application use are -

1. Used as a Bushing in PUMPS APPLICATION instead of HASTEALLOY, SS, NI HARDENED STEEL, CERAMICS etc.
2. Used as Gears in GEAR PUMPS (The only polymer which can withstand that high initial torques)
3. Used as gear & bush in HPLC’s in laboratory’s.
4. Wear rings & valve plates in compressors.
5. Mating rings of mechanical seal.
6. Aircraft parts.
7. High wear sliding bush in cable & wire industry etc

Any customized application which could be developed after learning the application.

3. Hydraulic stability.
4. Good mach inability.
5. High load bearing capacity.
6. Controlled co-efficient of friction.
7. Good bonding to metal, wood & plastics.
8. Oil grease & chemical resistance.
9. Ozone oxygen & radiation resistance.
10. Wide temperature stability (-40 to 100°C).

POLYURETHANE SPRINGS :

SHREE’S  polyurethane springs is the new wonder material which combines the strength of plastic & the elasticity of rubber. It eliminates the limitations of wire springs and rubber bushes. Wire springs have the tendency to break under high pressure and permanent set in a short time. It can sustain very high loads at higher hardness than rubber. Unlike rubber, It does not take part in weathering or chemical actions under normal conditions & does not disintegrate easily. Life expectancy is very high SHREE’S PU SPRING PADS are ideally suited to press tools, jigs, fixtures, conveyors, machine tools, etc. where the actions of stripping, dampening, cushioning, resting or rolling is involved.
