The Best Engineering Plastics for Extreme Heat
Polytetrafluoroethylene, also known as PTFE and Teflon, is a widely used plastic that was discovered in 1938 by the company Chemours. It has one of the highest melting points out of any plastic, 620°F (327°C), but it maintains its strength at temperatures as low as -450°F (-268°C).
Flame retardant plastic | Ensinger
UL94 V-0 plastic (vertical burning): The specimen is held in vertical position and is exposed for 10 seconds to direct flame on the bottom end. After 10 repeated ignitions, the sum of the time needed to stop burning after removal of the flame is made. If the total extinguishing time is below 50 seconds and no flaming drips occur, the material
Introducing Novel Flame Retardant Materials to Produce
To overcome these limitations, a novel flame retardant system has been investigated. Although still a filler, approximately 10 times less material is required to produce a flame retardant system, therefore making it possible to formulate a flame retardant encapsulation resin with viscosities of less than 700mPa s, whilst still meeting UL94 V-0.
- What are eco-friendly PVC flame-retardant plasticizers derived from renewable sources?
- Eco-friendly PVC flame-retardant plasticizers derived from renewable sources have received affection. A series of biobased flame-retardant plasticizes has been prepared from castor oil with phosphaphenanthrene (DOPO) and diethyl phosphate , , , , , .
- Are flexible poly (vinyl chloride) plasticizers flammable?
- Nevertheless, the combustibility of flexible poly (vinyl chloride) (PVC) products containing high content plasticizers is frequently disregarded. The development of PVC functional plasticizers requires careful consideration of a good balance between flame retardancy, migration resistance and plasticity through molecular structure design.
- What are biobased flame-retardant plasticizers?
- A series of biobased flame-retardant plasticizes has been prepared from castor oil with phosphaphenanthrene (DOPO) and diethyl phosphate , , , , , . The incorporation of these biobased plasticizers along with DOP into PVC afforded a material which exhibits commendable fire resistance in flame-retardant performance tests.
- Is plasticizer va8-p flame-retardant?
- To verify the flame-retardant behavior of plasticizer VA8-P, the surface of the combustion product was analyzed via scanning electron microscopy (SEM). The surface morphologies of the residue after combustion of various PVC blends are shown in Fig. 9.
- Do flame-retardant plasticizers reduce CO2 content and FGI?
- The CO 2 content and FGI of samples with added VA8-P were considerably reduced, indicating that the residual char layer formed by flame-retardant plasticizers during combustion caused incomplete sample combustion. Therefore, smoke and CO emissions increased, preventing heat transfer and flame spread.
- How to make flexible PVC fire resistant?
- The conventional approach to imparting fire resistance to flexible PVC involves the addition of supplementary flame retardants or additive, such as hydrated minerals, chlorinated paraffins, antimony oxide (as a flame-retardant precursor), inorganic phosphorus, phosphate esters and so on .
