Flame Retardant Additives for Polypropylene at Inolub

Polypropylene (PP) is a commodity plastic involved in a wide range of applications. It is an economical material that offers outstanding physical, chemical, mechanical, thermal, and electrical properties. For this reason development of flame retardant additives for polypropylene has become an important area of research. Different types of flame retardants have been used in PP, for example, halogen-based, phosphorus-based, silicon-based nitrogen-based, metal hydrate & oxide, and intumescent.

 

Mechanism of Flame Retardancy

Like other synthetic polymers, the high carbon and hydrogen content of Polypropylene (PP) makes it combustible. To enable PP to be used safely, Fire retardants are added in applications where an enhanced flame retardant capability is required. However, these additives don’t make the compound non-combustible, they make it more ignition resistant.

Flame retardants are added so that the flame spread time during burning can be considerably increased compared to the unmodified PP. It is considered that the burning of polymers like PP can be inhibited either in the condensed phase, dispersed, or gaseous phase in physical and /or chemical mode.

●     Dilution of the combustible content

●     Dissipation of heat, shielding of the surface by charring or forming of a glassy coating or gas or liquid barrier reducing the heat transfer

●     Altering of the distribution of the condensed pyrolyzates

●     Lowering of substrate’s temperature

 

If you are looking for a reliable manufacturer of flame retardants and anti dripping agents, you don’t need to look further. Here are the advantages of Inolub’s flame retardants and anti-dripping additives.

 

Advantages of Inolub’s flame retardants and anti dripping agents

●     In industrial applications, anti drippingadditives for plastics are used in combination with flame retardants to prevent burning plastics from dipping off and thus meeting the requirements of UL94.

●     Inolub’s Anti dripping agents are easy to handle and process, also impart excellent anti-drip properties to the material.

●     They are in the form of free-flowing powder which is highly effective at a low addition level.

●     Inolub manufactures additives that are widely compatible for use in various plastics.

Use Fire Retardant for Making your Polymers Fire Proof

Polymers are widely used in various applications. However, just like the majority of other organic compounds polymers are also flammable. These lightweight, high-performance polymeric materials offer many advantages in industrial as well as commercial applications, but they greatly increase the risk of fire because of their flammable property. To help overcome this issue Gujarat Fluorochemicals Limited (GFL) has come up with fluorine-based fire retardants catering to the material requirements of various industries.   Fire Retardant Chemistry   When a polymer comes into contact with flame, the following types of products are released: 1.     Combustible gases (like methane, ethane, and carbon monoxide) 2.     Noncombustible gases (like carbon dioxide, hydrogen bromide, and hydrogen chloride) 3.     Liquids which are partially degraded polymers 4.     Fine particles of the decomposing polymers 5.     Discrete solid in form of char or carbonaceous residue.     Among

How Flame Retardants & Anti Dripping Additives Function In Polymers?

The vast majority of polymer compounds which find a great many applications in diverse industries are inflammable. That's why these versatile materials sometimes find their usage being limited to those conditions where the probability of fire breaks are minimal.   Since we all are well aware that flames can take a monstrous form, destroying everything in its way, it is better to be safe than sorry. It is rightly said that prevention is better than cure. However, with a scientific mindset, we have not just one way to go about things but many. For enlarging the vast array of employment of polymer compounds, Gujarat Fluorochemicals Limited have come up with effective Anti Dripping Additives that don't let the polymer material drip away or catch fire easily when introduced to a flame.   Here is a rundown on how Flame Retardant Additives do their magic and make polymer compounds fireproof.   ●      Vapor Phase Inhibition . The flame retardant additives excellently di

Why Are Flame Retardant Additives Needed To Be Included In Plastics?

Fire consumes all in its way. The fierce flames are dreaded by all for the mass destruction they cause when they get out of control. People have wondered and gone into depths to discover what makes fire burn in pursuit of controlling it and using it to one's advantage.   It's no coincidence that the punishing ways in inferno utilise fire as a weapon to cause pain that's unbearable. When we get to it, we find that fire is nothing but a chemical reaction that produces vast amounts of heat. It ignites with the fire triangle that consists of oxygen, fuel and heat that sparks the reaction into action and these together bring havoc on earth. Take one out and you see fire breakouts deescalating and coming to a rest.   Requirement of Fire Retardant Additives in Plastics Plastics have become a part and parcel of our lives. With its countless applications in diverse sectors, people have to realise the need for fireproof plastics for safety. Also, Fire Retardant Additives
