We've Added New Vistalon Data Sheets

Last time we talked about ExxonMobil’s Vistamaxx grades. We’ll stay on the theme of ExxonMobil products, this time to talk about Vistalon. Vistalon is a range of ethylene propylene diene (EPDM) rubber grades that are designed to provide excellent heat (up to 175°C), ozone, and weather resistance. Vistalon also offers good water resistance, good electrical insulation and good low temperature flexibility. Additionally, it has good resistance to ketones, ordinary diluted acids, and alkalines.

Vistalon rubber grades are used in a wide variety of applications in the automotive, consumer, and industrial sectors. Common applications include: automotive belts, industrial belts and hoses, seals, gaskets, pads, electrical insulation, and roofing sheets. Vistalon can also be blended with other materials such as plastics and elastomers to adjust physical properties in the final compound. 

We’ve seen our customers benefit from Vistalon with improved processes, enhanced performance and increased value for their end-products. We recently added data sheets for several Vistalon grades for calendered, extruded and molded applications ranging from roofing membranes and water management to automotive weatherseal hoses and gaskets, to electrical connectors and compounds. Check out the data sheets here on our ExxonMobil Chemical Data Sheet page and contact us for formulations specific to your unique requirements.  

Vistamaxx case study: Golf Tee

Let’s talk about Vistamaxx.

Vistamaxx is a propylene-based elastomer (PBE) from Exxon Mobil Corporation. Elastomers such as Vistamaxx can be used to adjust and balance physical properties within polypropylene (PP) blends. Due to ethylene content levels, Vistamaxx PBE will be considerably softer than PP materials. This means that Vistamaxx can be used to adjust the flexibility, softness, toughness, or durability of a PP blend. Vistamaxx can also increase transparency and reduce stress whitening as well as accept coloring well, which can give your product increased visual appeal.  

We recently received samples of ExxonMobil’s latest Vistamaxx success showcase: a high-performance, durable golf tee. This particular application demonstrates Vistamaxx’s compatibility within homopolymer polypropylene (hPP). The stem is white with a pleasant gloss and 5-10% Vistamaxx 6202 (datasheet here) added into hPP to give the stem slight bendability which will increase its overall durability. The head is a vibrant orange-colored overmolded part composed of 90% Vistamaxx 6202 in hPP.

There are a few things to remember when adding elastomers to your hPP. Your additive ratio will greatly affect the physical properties of your final product. Higher concentrations of Vistamaxx will result is lower tensile strength and hardness and increased impact strength, elongation and flexibility. Furthermore, due to the fact that Vistamaxx will influence your overall material’s properties you may need to tweak your processing conditions to account for the change. This usually means you can lower your processing temperatures and make adjustments to processing speeds. Feel free to contact us if you have any questions regarding adding Vistamaxx to your materials.  

 

Wood plastic composite

Like the name implies, Wood-plastic composites (WPCs) are composite materials made of wood fiber/wood flour and thermoplastic(s)(includes PEPPPVC etc.).

Wood Plastic Composites (WPCs) are produced by thoroughly mixing ground wood particles and heated thermoplastic resin. The most common method of production is to extrude the material into the desired shape, though injection molding is also used. WPCs may be produced from either virgin or recycled thermoplastics including HDPE, LDPE, PVC, PP, ABS, PS, and PLA. Polyethylene based WPCs are by far the most common. 

There are many applications for WPC, for example, parquet application inside households, decking and fencing application in garden and outside uses, spa and bath floor applications, furniture and sports good applications etc.

 

SEBS

Kraton Performance Polymers produces some high-performance SEBS materials which include G1643 and G1645. These materials feature excellent durability, great organoleptics, UV resistance, and exceptional processing stability. In addition to single material applications, these grades can be easily dry-blended or compounded with PP for impact modification, improved transparency, overmolded parts and much more.

Wewill in Shanghai

Four representatives from Wewill Inc. will be going to Exxonmobil’s Vistamaxx™ 3-day technical training in Shanghai, China later this month. 

Vistamaxx™ grades can be used to reduce impact whitening, strengthen products, lower processing temperatures, and allow for downgauging. We have started preparations for this training session and look forward to seeing how our partners benefit from the information we bring back.
