General description
CDM DURAPOL 68910 is a composite material made of glass mat, combined with a high mechanical resistance resin system.
Static and its companion ESD (electrostatic discharge) damage electronic components and circuits every day. To use CDM
DURAPOL ESD will allow charges to move slowly out of the circuit and will ensure the quality of your production. CDM DURAPOL
ESD product have guaranteed dissipative characteristics.
The CDM DURAPOL range of products exhibits higher mechanical and resistance properties as standard composite materials.
The random glass mat substrate present in the CDM DURAPOL 68910 minimizes delaminations problems during machining or
pallet use.
The relative low thermal conductivity in the CDM DURAPOL materials allows quick pallet turnaround eliminating most of the time
both the necessity to provide a cooling station and the process heat sink effect experienced in the metallic pallets. CDM DURAPOL
materials can substitute metallic solder frames with great advantages.
This product was referenced as Durapol L 200 in the past.
Description
Flux resistance is depending on composition and pH level. CDM DURAPOL has been developed to have a better withstand towards
chemicals. To preserve the stability of CDM DURAPOL material, a regular cleaning can still be made. Due to the high fiberglass
content, machining is recommended with carbide or diamond toolings. Precise machining with very accurate tolerances can be
achieved by experts in the conception and machining of pallets.
