Durapol IGM L200 (previously named LRA)
- Constructed of 100% polyester resin and glass filament.
- Our most popular composite for use in soldering tooling. Excellent value/cost ratio
- Constructed from a proprietary polyester resin with a reinforcement of glass filament. Slight compliancy from polyester increases toughness, which allows thin wall cross-sections without fracture. This compliancy also causes the material to be less rigid than 100% epoxy composites but is more than sufficient for most applications.
- Consistently capable of 6k-12k passes through the wave solder process. Longevity is dependant on cleaning and allowing tooling to cool between cycles. Industry feedback indicates L200 is less reactive to fluxes, which cause premature breakdown in other materials.
- Excellent dimensional stability and will retain flatness through repeated reflow temperature cycling
- Superior machinability allows manufacturing to the tightest tolerances
- Good chemical resistance, not light detectable
Delmat CDM-ESD 68.610
- Constructed of epoxy resin, 5% polyester resin and approximately 65% glass filament.
- Excellent rigidity and dimensional stability to retain flatness through repeated reflow temperature cycling
- "Ability to withstand extreme temperatures without cracking, warping or shattering".
- Similar coefficient of thermal expansion to most pcb substrates thus avoiding any binding, warp, flex, or other tolerance issues
Durostone CAS761
- Constructed of epoxy resin, 5% polyester resin and approximately 65% glass filament.
- Very Similar to Delmat's composite characteristics
- Good chemical resistance.
- Similar properties of epoxy based composites
- Small sheet (1m x 2m) results in decreased sheet utilization
