Guangdong has the largest output of non-woven fabrics, so Guangzhou Petrochemical has an absolute geographical advantage. The non-woven special material CS820 produced here is also very representative in China. This product is produced using Japan's Mitsui Oil Chemical HYPOL production process technology with world advanced level. It has the characteristics of high fluidity, narrow molecular weight distribution, good processing performance, non-toxic and odorless. Products are widely used in composite filaments, staple fibers and textiles.

Brass Nut

Copper nuts made of all kinds of embossed wire (usually lead brass, such as H59, 3604, 3602). Our daily contact with the embedded knurled copper nuts are processed by precision automatic lathes. The reference standard of embedded knurled copper nut comes from GB/T809, but the technical parameters of all kinds of embedded nuts produced by our company exceed the relevant indexes required by the national standard.

Knurling copper nut is mainly used for hardware Spring, shaped spring, craft gift spring, battery spring, spring antenna,key ring, phosphorus copper spring CNC automatic lathe turning parts (copper car parts, iron, aluminum car parts), metal stamping parts, electronic parts, iron shaft, single Rachel,Rachel, iron pin, non-standard Screw nut,fittings,fasteners, wire forming (wire card holder, Model aircraft landing gear, S hook, R latch, triangle buckle, D buckle) and other hardware products, belonging to the copper nut series.
