Advantages: Good corrosion resistance: Marine Resin has good corrosion resistance and can resist the erosion of corrosive media such as sea water and salt spray, extending the service life of the ship.
Application scenarios: Hull manufacturing: Marine Resin is used to make structural components of the hull, such as bottom, hull, deck, etc., which can improve the strength, stiffness and corrosion resistance of the hull.

FAQ
Our Advantages
Why we choose Changzhou Rule Composite Material Co., Ltd?
What is resin?
Resin usually refers to products inclined to softening or melting after receiving heat. When softening, it shows a trend toward flowing under the influence of external forces. Under normal temperature, it is in solid, semi-solid state, and sometimes liquid organic polymer. Broadly speaking, any macromolecule compound that can be used as a raw material for plastic processing can be called resin.
What can resins do for you?
Resin products are widely used in sectors like railways, automobiles, wind power, shipbuilding, cooling towers, pipelines, coatings, electrical appliances, artificial stone, handicrafts, lighting tiles, sanitary ware, anti-corrosion engineering and so on. Rule has been granted certification of ISO9001: 2008 Quality Management System and ISO14001: 2004 Environmental Management System, and some products have won recognition of China Classification Society(CCS) and Food-Level Licenses of the Provincial Department of Health.
