Melting Materials Dripping Test Machine
The Melting Materials Dripping Test Machine is designed to evaluate the melting and dripping behavior of materials exposed to radiant heat. It is suitable for testing automotive interior materials according to the applicable requirements of UN Regulation No. 118, Annex 7.
The instrument uses a 500 W electric radiator to heat the specimen under controlled conditions. A stainless steel mesh specimen holder supports the sample, while a collection container catches molten droplets for observation. The test helps determine whether the material melts, drips, or produces flaming droplets when exposed to heat. It is suitable for automotive material manufacturers and fire testing laboratories.
Application
(1) Automotive interior materials
(2) Thermoplastic materials
(3) Polymer sheets and components
(4) Materials used in vehicle interior construction
(5) Heat-exposed materials requiring melting and dripping evaluation
(6) Fire performance testing laboratories
