1) Alcryn(R) - What is it?

Alcryn® is a true thermoplastic elastomer, based on a partially cross-linked, chlorinated olefin interpolymer alloy. It is designed for the manufacture of rubber parts with high productivity on thermoplastic processing equipment.

It Processes Like a Thermoplastic
Alcryn® melt-processible rubber:

• does not require pre-drying for most processes.
• is ready to use as received, no compounding required.
• does not require vulcanization.
• can be injection-molded, extruded, blow-molded, calendered, and vacuum-formed.
• can be processed on plastics equipment.
• can be coextruded and calender-laminated with PVC, without adhesives.
• can be overmolded on selected rigid substrates.
• molds in short cycles (high production rates).
• produces recyclable scrap.
• fast efficient processing, without the need for compounding and vulcanization, yields low operating and part costs.

It Behaves Like a Rubber
Alcryn® melt-processible rubber:

• looks, feels, and performs like flexible vulcanized rubber.
• has outstanding weather and ozone resistance.
• has excellent oil and heat resistance.
• is energy absorbing for noise and vibration abatement.
• provides a service temperature range of -40 degrees to 225 degrees F (-40 degrees to 107 degrees C).

Typical Applications
Alcryn® offers high value-in-use for many applications now served by vulcanized rubbers, other thermoplastic elastomers, and flexible thermoplastics, including:

• Window and door weatherstripping (and other complex profile extrusions).
• Injection-molded parts.
• Coated fabrics and sheet goods.
• Blow-molded parts.
• Seals and gaskets.
• Tubing and hose.
• Wire and cable jackets.
• Soft handles and grips.
