PP-T22 (talc-filled)

LyondellBasell · Hifax TYC 852X E BLACK

Hifax TYC 852X E is a polypropylene copolymer with 22 percent talc that LyondellBasell designed for automotive bumpers: high flowability, high impact resistance and a low coefficient of linear thermal expansion. The material is in development with us.

This material is still under evaluation at our site

We have it in house and are working towards process release, but it is not yet qualified. We therefore cannot commit to it for series parts. If it suits your application, talk to us – we will tell you openly where we stand, and we can use it as part of a trial.

These values are taken from the manufacturer datasheet and apply to the material, not to the printed part. In 3D printing the achievable properties depend on part orientation, layer height and process parameters – in the Z direction in particular they are lower. Please talk to us before relying on them for design.

Strengths

  • High impact strength: 45 kJ/m² notched at 23 °C (Charpy)
  • Low coefficient of thermal expansion according to the manufacturer – less dimensional change with temperature swings
  • Good flowability: melt mass-flow rate 31 g/10 min at 230 °C / 2.16 kg
  • Light: 1.06 g/cm³ despite 22 % talc content
  • Talc instead of glass fibre: less abrasive, easier on nozzle and screw
  • Paintable according to the datasheet

Limitations

  • Not yet qualified on our machine – please treat as an enquiry
  • Impact strength collapses in the cold: 3.5 kJ/m² notched at −40 °C compared with 45 kJ/m² at 23 °C
  • Heat resistant only up to 100 °C (HDT B, 0.45 MPa); the datasheet gives no HDT A
  • Tensile strength, elongation at break and shrinkage are missing from the datasheet – LyondellBasell asks to be contacted about shrinkage
  • The manufacturer expressly excludes medical, pharmaceutical, food and drinking water applications

Typical applications

  • Bumpers and add-on parts in vehicle construction (field of use according to the manufacturer)
  • Cladding and covers exposed to impact
  • Large-area parts requiring low thermal expansion
  • Painted visible parts
