GPO-3 Sheet Strength
With superior compressive strength, flexural strength, tensile strength, the material shows excellent mechanical properties even in different environments ( temperature, medium, humidity)under various roads (tensile, compression, bending, torsion, impact, alternating stress, etc)
With superior casting resistance, cutting resistance, welding resistance, stamping resistance, heat treatment performance. With a special metal processing equipment can easily work out molding products.
With stable dimension, the actual parameter value for thickness with very small variation, no need for further processing can accord with the requirements for thickness tolerance.
With excellent stable mechanical properties even in the high humidity environment, can prevent the solid insulation material surface form a conductive path under the join action of electric field and electrolyte gradually.
Resistant caused by high voltage arc metamorphism effectively.(more than 180s)
With very high working temperature: when temperature over 240℃ will be deformation. The grade for heat resistance can be F or H.
The materials for slow down, terminate or prevent flammability properties meet the requirements of American UL94 V-O; Not included halogen elements, with little smog in cause the material is lighted.
With good hot mechanical properties, can keep an excellent mechanical and electrical properties even in the continuous rising temperature.
With excellent Comparative Tracking index (CTI>600V)
