PROS AND CONS OF POLYESTER ENCLOSURES
Why polyester enclosures? β MBP
PROS |
CONS |
β Good chemical resistance | β Does not meet high optical demands due to glass fibre content |
β No softeners/elastomers in the base material | β Higher weight compared to thermoplastics |
β Absolutely corrosion-free even under mechanical impact (stone chips and scratches) | β Limited choice of colours |
β High stability and impact resistance due to glass fibre reinforcement | β Low heat conductivity |
β UV-stable and weatherproof | β Machines with dust extraction system for mechanical processing recommended |
β Protective insulation of installed components | |
β Self-extinguishing and flame retardant |
