The manufacture of thermoplastic powders with the addition of liquid nitrogen (N2) is also cryogenic grinding.
Midwest Elastomers specializes toll grinding plastic polymers, adhesives and ingredients. to the polymer industry. Our equipment consists of granulators, hammer mills, attrition mills, rolls mills for cryogenics, ambient grinding, and classification. We are experienced in producing acrylic polystyrene, polyester, ABS, PVC, TPE, TPU, polypropylene, nylon, EVA, adhesives and more.  A lso recognized under the brand names of Plexiglas and Lucite, acrylic is an optically clear, transparent material having outstanding weather resistance, high impact strength, good chemical resistance, and is easily thermoformed and fabricated. Formulations include sheet, rod and tube. PVDF Polyvinylidene Fluoride PVDF, manufactured under the names of Kynar and Hylar, is a high performance thermoplastic that combines great mechanical strength and high abrasion resistance with a broad temperature range. It is highly resistant to most environmental conditions and corrosive materials.

It is highly resistant to most environmental conditions and corrosive materials. Obviously, ease of cleaning is critical for systems that process spices, neutraceuticals and pharmaceuticals because of food safety and hygiene concerns. Ease of cleaning is also important in the processing of plastic resins because many processors like to use a single grinding system to process a range of products. As a result, these systems must be thoroughly cleaned to prevent cross-contamination among products. Achieving a high level of cleanliness when alternating among different products in the processing of thermoplastic powder coatings is especially important when, for example, different resin colors are involved. Particle size classification equipment such as a screener is not used to classify the particles by size, and it recycles the over-size materials to the feed.This type of test provides insight into the grinding mill’s size reduction capabilities. RTI Cryogenics Inc. has the technology to produce a 100% recycled thermoplastic elastomer (TPE) pellet from recycled cryo crumb rubber and recycled post-industrial and post-consumer plastic. This pellet is called XyComTM TPE and it is sold under a 10 year take or pay, global Off Take Agreement. Our vision is to become the world leader in Value Added Tire Recycling by installing at least 15 of RTI's turnkey patent pending XyComTM TPE plants worldwide in the next 3 years. 60 YEARS OF COMPETENCE IN POWDER GRINDING (Toll Grinding). The manufacture of thermoplastic powders with the addition of liquid nitrogen (N2), also called cryogenic grinding, requires not only significant know-how but also state-of-the-art equipment. We accept grinding orders from 200 kg (single orders) to 500,000 kg (annual orders). Depending on customer requirements, the finished powders can be packaged and delivered in bags (20 kg), carton barrels or Big Bags (500 kg, 700 kg, 1000 kg). Emerging technologies in biosciences, pharmaceutical research, physics equipment, and space flight hardware require materials capable of operating at cryogenic temperatures. Applications include bearings, seals, and thermal insulators. With helpful charts and graphs, its perfect for engineers, specifiers, and buyers involved in cold temperature storage and processing equipment, spacecraft hardware, particle accelerators, cryogenically cooled supercomputers, pharmaceutical and biosciences applications, and superconducting magnets. Plastic materials offer a number of benefits for cryogenic applications including : The purpose of this white paper is to describe the mechanical, thermal, and friction and wear behavior of plastics at cryogenic temperatures. It includes important considerations as engineers design devices that must operate at low temperatures. With helpful charts and graphs, its perfect for engineers, specifiers, and buyers involved in cold temperature storage and processing equipment, spacecraft hardware, particle accelerators, cryogenically cooled supercomputers, pharmaceutical and biosciences applications, and superconducting magnets. It can be used in many of the same applications as acrylic when impact strength is a factor. Some common uses are as safety shields and enclosures, sight glasses and chair mats. PVC Polyvinyl Chloride. PVC sheet is medium impact, high corrosion resistant material, ideally suited where chemical resistance is necessary. PVDF Polyvinylidene Fluoride PVDF, manufactured under the names of Kynar and Hylar, is a high performance thermoplastic that combines great mechanical strength and high abrasion resistance with a broad temperature range. It is highly resistant to most environmental conditions and corrosive materials.
