Cut to Length Shear Knives

Operational Progress: Steel-making - Blanking - Forging - Rough Processing - Heat Treatment - Finishing - Testing Other Information: Renke is a leading machine knife manufacturer in China, offering a wide range of straight knives suitable for both hot rolling and cold rolling applications. Our products are designed to meet the highest standards of quality and performance. 1. Straight Knives for Hot Rolling Applications: These knives, including shear blades, are typically made from high-quality steels such as nickel alloys. They are ideal for use in high-temperature environments where durability and precision are essential. 2. Straight Knives for Cold Rolling Applications: For cold rolling, we use medium and high-quality alloy tool steel and heavy-duty powder metallurgy steel. Shear blades for plate shearing machines come in various sizes and specifications to suit different cutting needs.

Polyether Polyols

This series products are the block and random copolymers made from allyl alcohol, EO and PO. And they are main materials for synthesizing polyether polysiloxane. Polyether modified polysiloxane can dissolve in the water and oil, and it is easy to regulate. It has all the excellent performances of the traditional polysiloxane product, in the meanwhile, it has the function of the lubricating, softening, good spreading and emulsification stability offered by polyether chains. And it can be used as PU foam stabilizers, textile auxiliary, oil field demulsifier, cosmetic auxiliary, coating leveling agent, detergent, defoaming agent and emulsifier etc. the copolymer of the polyether reacting with hydrogen containing silicone oil can be applied as PU foam stabilizers , textile auxiliary, oil field demulsifier and emulsifier etc..
