FlexPro TPE Thermoplastic Elastomer BS-TP700

When Precision Meets Flexibility on the Factory Floor

In a high-volume automotive parts plant in southern Germany, engineers struggled to find a material that could deliver the soft-touch grip of rubber while running on standard injection-molding equipment. Switching to FlexPro TPE BS-TP700 eliminated the need for secondary vulcanization, cut cycle times by 22%, and gave their overmolded tool handles a premium feel that end-users immediately noticed.

That story repeats across industries—from medical device housings to power-tool grips, appliance seals to sporting goods. FlexPro BS-TP700 is engineered to be the one material that replaces cross-linked rubber in applications where speed, recyclability, and surface quality matter.

Key Performance Parameters

FlexPro BS-TP700 is a styrenic-block-based thermoplastic elastomer supplied as uniform 2–3 mm pellets. Below are the characteristics that make it a go-to choice for demanding industrial applications:

• Hardness range: Shore A 30–90, tunable by blending with polyolefin carriers
• Tensile strength: ≥ 12 MPa at break, elongation > 450%
• Compression set: < 25% after 22 h at 70 °C — outperforms many conventional TPVs
• Processing temperature: 170–210 °C on standard screw injection machines
• Specific gravity: 0.92–1.05 g/cm³, lighter than PVC and most rubbers

Every batch is tested for melt-flow index, color consistency, and pellet dimensional tolerance before release, ensuring your process engineers see the same behavior from the first shot to the ten-thousandth.

Processing Guidelines for Industrial Users

Getting the most from FlexPro BS-TP700 starts with proper material handling. Pre-dry pellets at 80 °C for 2 hours if ambient humidity exceeds 60%. Barrel profile recommendations: Zone 1 at 175 °C, Zone 2–3 at 190 °C, nozzle at 200 °C. Mold temperature between 20–40 °C yields the best surface finish for overmolding onto ABS, PC, and PA substrates.

Recycling & Sustainability

Unlike thermoset rubber, FlexPro BS-TP700 sprues and rejected parts can be reground and reprocessed at up to 25% blend ratio without measurable loss in mechanical properties. The material is REACH-compliant, halogen-free, and meets RoHS 2.0 directives — making it a responsible choice for export-oriented manufacturers targeting EU and North American markets.

Whether you are sealing an automotive gasket, overmolding a power-tool handle, or extruding a soft-touch tubing profile, FlexPro BS-TP700 delivers the elasticity of rubber with the processing economics of thermoplastics.
