Knowledge center
In material selection and mass production, engineers meet the same questions again and again. How does a flammability rating relate to thickness? What is the difference between halogen-free and fluorine-free? Why does PC/ABS show splay marks? The knowledge center answers these questions in short articles. Every article states the conditions it applies to and its data sources.
Thickness 3.0 mm
May be V-0 at 3.0 mm
V-0: Afterflame time of each specimen after each flame application ≤ 10 s

How to read a UL 94 flammability rating: why thickness always matters
An engineer chose a material labeled "V-0". The part wall is 1.0 mm. After testing, the part did not reach V-0. What went wrong?
Halogen-free and fluorine-free flame retardants: how halogens, PTFE and PFAS relate
Many electronics and appliance brands have added two requirements to their material specifications:
Drying and molding PC/ABS: avoiding splay, brittle failure and loss of flame retardancy
PC/ABS pellets absorb moisture from the air. In injection molding the melt is above 230 °C. At that temperature, moisture:
