Exact Plastomers

What are Exact plastomers ?

Exact plastomers are a range of low density ethylene copolymers made possible by combining Exxpol metallocene catalyst technology with the Compact solution polymerisation process. The comonomer used by DEXPlastomers is octene. As the name implies, Exact plastomers bridge the gap between plastics and elastomers. They exhibit many of the physical properties of a rubber and combine this with the processing advantages of a thermoplastic. With the unique molecular structure delivered by Exxpol catalysts, has opened a whole new range of products design and fabrication opportunities.

What do Exact plastomers bring ?

Exxpol metallocene catalyst technology affords a highly efficient and consistent incorporation of octene comonomer into a polyethylene backbone. This results in low density and ensures precisely defined polymers with a range of unique performance attributes:

Sealing Lower peak melting points and narrower melting ranges providing controlled sealing performance and superior sealing through contaminations.  Flexibility   Flexural modulus similar to elastomers and thermoplastic behavior without plasticizers or polar comonomers.  Compatibility   Exceptional compatibility with other polymers and elastomers to provide tailored attribute blending opportunities.  Processability   Free flowing pellets for continuous compounding. Processable on conventional extruders.   While these are the dominant features, many other benefits of these unique Exxpol catalysed products are also exploited in product design : outstanding clarity very low extractables exceptional toughness high filler acceptance efficient peroxide and silane crosslinking surface softness anti-slip behaviour The unique combination of attributes offered by Exact plastomers opens the possibility to improve your existing products range, reduce costs and expand into new end-uses and markets.   In which applications bring Exact plastomers value? Exact plastomers add value in a wide range of film, extrusion and moulding applications. For many applications, the plastomer attributes have been demonstrated to exceed the requirements. As a result Exact plastomers are extensively used as blend partner, offering the opportunity to tailor the performance to cost balance of finished articles. Just a few typical examples of applications are tabled below. Application   Exact Flexible packaging   Maximizes sealing performance for clean as well as contaminated seal areas, even at reduced temperatures. Display film   Adds to toughness and shrink performance. Blown stretch cling layers   Contributes to cling and low unwinding noise. Protective film   Enhances adhesion and affords removal without leaving stains. PP film   Improves low temperature impact resistance. Automotive sound deadening sheets   Affords high filler loading at required mechanical properties. Flexible TPO’s   Offers free flowing pellets for continuous compounding with PP for use in automotive parts, appliances and mechanical goods. Calendared sheets for building and construction   Optimizes flexibility-toughness balance of sheets for use in halogen free roof coverings, tunnel lining, geomembranes, coated fabrics. Wire and cable   Provides carrier for halogen free compounds for low voltage insulation and bedding. Adds flexibility in  cross-linked compounds. Masterbatch carrier   Affords low temperature blending and contributes to filler acceptance and dispersion. Synthetic corks   Combines ease of foaming with superior odor and off-taste performance compared to other polymers used such as EVA, SEBS. Artificial grass   Enhances yarn softness and resilience. Soft foams   Produces flexible, resilient foams suitable for application in lightweight applications such as footwear. Non wovens   Enhances bond strength and softness Exact plastomers have shown commercial success in a many other applications requiring improved sealing and low modulus polymers.
