Our cellulose based board is available in various densities and manufacturing
methods - hot-press-dried, LAMINATED or corrugated structures.
All confirms to IEC, JIS, DIN, BS, ANSI, ASTM standards.
Our Pressboard ensures long-term dimensional stability.
Laminating of hot-press-dried Pressboard will result
in a higher thickness more than 8.0 mm. The range of thickness of laminated
PRESSBOARD begins from 9.0 mm up to 50.0 mm. Laminated material is, like
hot-press-dried PRESSBOARD, dimensionally stable and offers highest mechanical
and electrical strength. The resins in use are casein and polyester glues;
casein is aqueous, polyester is non-aqueous.
 Typical
applications of laminated PRESSBOARD are pressure rings, static rings,
beams, clamping plates and support strips etc. in power, distribution
and special transformers.
These products made from highly purified unbleached
softwood pulp which import from Russia and Canada. They have obvious good
properties in mechanical strength electrical strength and compressibility
is used world wide as insulation material for transformers reactor and
bushing current transformer in the electric transmittal field.
