Add polyurethane flame retardant
Three (2-chloroethyl) phosphate (TCEP) is a type of added polyurethane flame retardant that can be used in polyurethane soft foam and hard foam production. However, it is better to use for hard foaming effect because of high porosity and low permeability. It is difficult to add polyurethane flame retardants, and the flame retardant effect is maintained for a long time.
Its disadvantage is that the dosage is larger, and if the dosage is more than 15%, the property of foam plastics will decrease. TCEP is widely used in flame retardant polyurethane foam plastics, and 10%TCEP can be obtained in polyurethane hard or semi-hard foam. Using TCEP to reduce the brittleness of the blisters without weakening the corrosion resistance of the foam.
When TCEP is used for polyurethane soft foam, such as flame retardant modified high rebound foam, TCEP can be used in combination with melamine. TCEP can be used as a separate component to inject the mixed head directly in the foaming process, also can be mixed with polyether polyol before foaming, and can reduce the viscosity of polyalcohol component.
TCEP is the earliest and most widely used flame retardant, it has good resistance to hydrolysis and high flame retardant efficiency, but it is easy to lose and the flame retardant durability is poor.
Today's automotive industry is moving towards high performance, low weight, comfort and security. Xiangsu synthetic materials are gradually replacing metal materials, which has opened up a promising prospect for the application of polyurethane elastomers. Second generation TPU.
The product maintains the characteristics of the first generation TPU Estaloc, and USES the hollow glass ball as filler, which increases the gloss of the gloss by more than 15, which can be used in the manufacturing of side plates and cushioning MATS. The installation of airbags in the car is the need of the development of modern automobile industry, which has a great effect on the safety of the driver's life. The airbag must have a certain strength to withstand the high speed impact, and also has a good low temperature flexibility, suitable for the production of polyurethane, the market demand is very large.
Polyurethane rubber can be used in the field of plastic runway of track and field, including basketball, volleyball, badminton and tennis courts, with two types: indoor and outdoor. This kind of plastic field is longer than wooden floor, wear-resisting, oil resistance, weather aging, elastic suitability, good performance of vibration, and solid foundation. Traditional asphalt felt
The waterproof material has been gradually replaced by the solid and durable polyurethane waterproof material. Stadium runway, large bridge expansion joint, the airport runway and highway also began to use room temperature curing of caulking polyvinyl chloride ester elastomer is used for making high speed railway sleeper is ideal material. The sleeper used in the tunnels and Bridges used by the Shinkansen railway in Japan is made of polychlorinated elastomer material. This new application has fully utilized the characteristics of the polychloric acid elastomer with light, vibration absorption and aging resistance, which has great promotion value.
Tris(2-chloroethyl)phosphate(TCEP)Use:
1. Tris (2-Chloroethyl) Phosphate Has Excellent Flame Retardancy, Excellent Resistance To Low Temperature And UV Resistance, The Steam Can Only Be Used At 225 ℃ Above The Direct Ignition Can Be Fired, But The Fire The Source Is Immediately Self-Extinguishing. This Product Is A Flame Retardant Not Only Can Improve The Material Level Of Flame Retardant Materials, But Also Improve The Flame Resistance Of Water Resistance, Acid Resistance, Cold Resistance And Antistatic Properties. Commonly Used In Flame Retardant Nitrocellulose And Acetate Fiber As The Substrate Of Paint Coatings, Unsaturated Polyester, Polyurethane, Acrylic, Phenolic Resin, Can Also Be Used For Soft PVC Plastic Flame Retardant. This Product Is Used For The Amount Of Unsaturated Polyester 10% To 20%, In The Polyurethane Rigid Foam (Flame Retardant Polyether As Raw Material) Can Be About 10% In The Soft PVC Used As Auxiliary Plastic Flame Retardant When The 5% To 10%. Flame Retardants, Uranium, Thorium, Plutonium, Technetium And Other Rare Metal Separation Solvent Or Extractant.
2. This Product Is Widely Used In Chemical Fiber Fabrics, Cellulose Acetate As A Flame Retardant, In Addition To Self-Extinguishing, But Also Improve Water Resistance, Cold Resistance And Antistatic Properties. The General Amount Of 5 To 10 Copies. This Product Is An Excellent Flame Retardant For Synthetic Materials, And Has A Good Role In The Promotion, Widely Used In Cellulose Acetate, Nitrocellulose Varnish, Ethyl Cellulose, Polyvinyl Chloride, Polyvinyl Acetate, Polyurethane, Phenolic Resin , In Addition To Self-Extinguishing Products, But Also Improve The Physical Properties Of Products, Products Feel Soft, Also Known As Oil Additives And Rare Elements Of The Extractant, And Flame Retardant Rubber Conveyor Belt Is The Main Flame Retardant Materials , The General Amount Of Added 5% To 10%.
3. Used As Additive Type Halogenated Phosphate Flame Retardant And Plasticizer. Molecules In Both Phosphorus And Chlorine, Flame Retardant Effect Is Remarkable, Not Volatile And Hydrolysis, Good Stability To Ultraviolet Light. Applicable To Phenolic Resin, Polyvinyl Chloride, Polyvinyl Acetate, Polyurethane And So On. Also Used As Nitrocellulose Coating Flame Retardant, PVC Flame Retardant Plasticizer, Metal Extractant, Gasoline Additives And Polyimide Processing Aids And So On. Can Improve Water Resistance, Weatherability, Cold Resistance, Antistatic Property. Reference Dosage 5% To 20%.
Polyurethane tyres are made of cast-casting process and their structure is very different from that of current tyres. The full polyurethane pneumatic tyre is made up of the foetus, the belt and the tread. Some polyurethane inflating tires come in two forms: one is the polyurethane which is cast in the body, while the tread is made of rubber for ordinary tires. The other is the fetal body as the meridional matrix, while the tread is polyurethane.
The chemical structure of polyurethane resin ensures good stability of the tyre. Due to the polyurethane resin is a kind of complete reaction of the polymer, its are both connected by chemical bonds between the molecules, thus avoided by oxidation or by other chemicals leaching, so as to prolong the service life of tires in theory. For rubber, due to the left in the vulcanization process of bonding part will continue to react with the change of the rubber, the rubber is very prone to hardening, the problem such as craze, so as to speed up the spare tire replacement frequency. For tire rolling resistance indicators (this is the key point for tires)
The rolling resistance of polyurethane resin tires is 45% smaller than that of conventional tires, since polyurethane resin tires can be made very round, which can help reduce rolling resistance. It is estimated that cars equipped with polyurethane resin tires can save up to 10 percent less fuel than cars with traditional rubber tires. Polyurethane resin is adopted
The actual driving distance is 1 ~ 2 times higher than that of ordinary tires, while eliminating a large amount of carbon black and aromatic oil pollution to the environment is a new way to improve the performance of the refurbished tyres.
It can be used for bandages, cardiac aid, blood pump, artificial blood vessel, artificial kidney, artificial ventricle, etc., using the physiological compatibility of PU elastomer and the advantages of anti-thrombotic. Good biocompatibility, blood compatibility and no additives are important reasons for the application of TPU and CPU materials in medical field. It has been developed successfully
Medical elastomers include: trachea cannula, prosthesis, family planning suppository, cranial defect repair materials, condoms, etc., and its application in medical and health field is very promising.
