We are a reckoned Supplier of Paper Phenolics in Gujarat, India. The Phenolics are designed and prepared by our team of adroit professionals under the stringent supervision of experts. They are obtained by pressing the multiple layers of resin impregnated filler materials in hydraulic press under high temperature & high pressure. The Phenolics are available with us in number of grades, which are tailored to meet international quality standards. They are widely used as insulating material.

Grades: Characteristics and Application :
E-P1 : Very good mechanical & adequate electrical properties, suitable for low-tension, non- humid application
Applications: Battery eliminator, transformer & choke bobbin, tube light ends, control panel, condenser mountings, drill back up and drill entry and bobbin industries.

E-P2 : Combination of good electrical & mechanical properties especially suitable for power industry and use in oil.
Applications: Transformer covers, C.B.handles and side frames, distribution board fuse base etc.

E-P3 : Excellent electrical and adequate mechanical properties, low water absorption suitable for high tension electric applications even under tropical conditions.
Applications: Transformer & choke bobbin for power electronic, relay spacers, grid covers, selector bank insulation etc.
