Frequently Asked Questions
Questions About Our Engineering Plastics?
Find answers to common questions about minimum order quantities, custom compounds, batch quality control and international supply. For application-specific questions, our technical team can review your material and performance requirements.
Standard PEEK, PPSU, PEI, PSU and PPS grades may start from 25 kg, or one standard bag. Custom colors, reinforced compounds and application-specific formulations generally require a higher quantity based on the selected formulation and production process.
Yes. We support functional compounding with carbon fiber, glass fiber, PTFE, ESD, wear-resistant, flame-retardant and custom-color formulations. Material development is based on your mechanical, thermal, electrical and processing needs.
Depending on the grade, each batch may be checked for melt flow, density, moisture, color and mechanical properties. A Certificate of Analysis and technical data sheet can be supplied where applicable.
Yes. We support customers in Europe, North America, Southeast Asia and other markets with English-language communication, shipping documents, technical data and available grade-specific compliance reports.
