Technical support

More than
materials.
Technical partnership.

Technical service is indispensable to our customers. When a production issue arises, prompt action is needed — we advise on a solution according to the conditions of the issue.

01

Material selection

Choosing the right grade for the part and the process.

  • Checking the compatibility of materials, additives and fillers
  • Standard, UV, mould-release, flame-retardant, glass- and carbon-fibre polycarbonate grades
  • Recycled PC, PPS, PEI and PEEK options
02

Processing guidance

Drying and moulding conditions for every grade.

  • Pre-drying polycarbonate to below 0.02% moisture
  • Cylinder, mould and pressure settings per grade
  • A processing guide for K, KG and RS-1340 grades
03

Technical analysis

Understanding the material and the moulded part.

  • Analysing materials, moulded parts, additives and fillers
  • Verifying conformance with specifications
  • Colour matching to customers’ samples
04

Troubleshooting

Prompt action when a production issue arises.

  • Advice on a solution according to the conditions of the issue
  • Improving machine parameters
05

Application support

From the design of the part to a tailor-made material.

  • Improving the design of parts and moulds
  • Developing new formulations to meet customer specifications
  • Tailor-made and toll compounding

know-how

01 · Processing guide

Pre-drying and injection moulding

Dry pellets to below 0.02% moisture — 4 h+ at 120 °C in a tray dryer. Cylinder, mould and pressure settings for K, KG and RS-1340 grades.

02 · Chemical resistance

Resistance to common chemicals

Polycarbonate resin is generally stable in weak acidic environments but degrades in alkaline and aromatic environments. Resistance was tested at 23 °C and may vary at higher temperatures.
