Data Sheet Alcryn Melt Processible ® Rubber What Is Alcryn MPR? Product Line Alcryn  The grades of Alcryn  MPR are grouped into four series:  melt-Processible rubber (MPR) is a true rubber, based on a partially cross-linked, chlorinated olefin interpolymer alloy. Alcryn  is designed for the manufacture of rubber parts with high productivity on thermoplastic processing equipment. It Processes Like a Thermoplastic Alcryn  MPR--a family of mid-performance elastomers that:   does not require pre-drying for most processes is ready to use as received, no compounding required  does not require vulcanization   can be processed on plastics equipment can be injection-molded, extruded, blow-molded, calendered, and vacuum-formed can be co-extruded, co-injected and calenderlaminated with PVC, without adhesives can be overmolded and co-injected 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.  1000 Series (black)  general plastic processing  not suitable for injection molding  excellent weather resistance  2000 Series (black, neutral, and translucent)  high-flow in all plastic processing  designed for injection molding  excellent for complex extrusions  not suitable for Calendering  black grades have excellent weather resistance  neutral and translucent require additives* for maximum weather resistance  3000 Series (neutral)  general plastic processing  not suitable for injection molding  requires additives* for weather resistance  4600 Series (black and neutral)  moderate flow in general plastic processing  not recommended for injection molding  excellent for complex extrusions  black grades have excellent weather resistance Within a series, the individual grades differ in hardness and related mechanical properties such as stiffness and tear strength. (Refer to the properties table for the relationship between hardness and mechanical properties.)  *pigments/UV stabilizers It Behaves Like a Rubber Alcryn  brings the end user a unique and highly desirable combination of functional rubber properties and environmental resistance. Alcryn  MPR:      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 -130° to 225°F (-90° to 107°C) Applications MPR 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) Soft handles and grips       Molded seals and gaskets Injection-molded and co-injection molded parts Blow-molded parts Tubing and hose Wire and cable jackets Coated fabrics and sheet goods Table 1.
