In this post, we present Total offer for Compounds, which includes one of Total most innovative brands, Bio-TPSeal®, specialized in special applications (specific and tailor-made compounds), and rotomolded products such as Fuel tanks.
Resins for compounders
Total wide range of natural resins in Polyethylene (PEHD, EVA, PELD), provides many options to help Polyproylene and Polystyrene compounders develop new innovative compounds in a lot of different fields, ranging from masterbatches to appliances.
All the flebility and properties required for a good compoundability are provided by the unique characteristics of Total materials.
Special applications. Specific and tailor-made compounds
To respond to the needs of some very specific and demanding markets, Total has developed specialty compounds such as electrically conductive compounds for industrial packaging industry. Along with the specialty compounds, Total also has different tailor-made possibilities dedicated to the rotomolding industry.
Bio-TPSeal®
Bio-TPSeal® is a proprietary alloy of metallocene PE and PLA (a polyester derived from natural resources).
Product benefits
- Low shrinkage and low warpage
- Good surface aesthetics and gloss
- High stiffness
- 100% recyclable
- Can be used in multilayer structures:
- Paintable with PLA top-layer
- In skin-foam-skin applications with TPSeal® for foaming
- Bonds with PU foam
Applications in rotomolding
- Automotive (replacing polyester, metals…)
- Design (low warpage and high gloss)
- Light weight, high strength parts
