What is the difference between platinum and peroxide curing?

when we talk near platinum or peroxide curing in the silicone world, curing is when the silicone rubber is chemically cross-associated by indicate of the addition of a peroxide or platinum curing agent.

The curing agents contend chemically to give the consequence produce, in this conjuncture silicone, different properties. Here we look at the positives and negatives of each system to force it clearer when determine on what silicone material you request for your poultice.

Peroxide Cured Silicone

Positives

Easier to projection – needs less constitution to dog the silicone

Once mixed, a peroxide dog silicone compound has a vastly mahaut shelf life so can be stored and custom for longer

Generally cheaper to buy the unpracticed ingredients so more competitory excellence

Tried and tested systems and the industry criterion

Negatives

Sheets and tubing not as clear as platinum heal silicone. Peroxide is more transparent in appearance rather than transparent

Needs talc or an exordium of a shim to prevent the silicone sticking to itself peculiarly when manufacturing silicone sheeting

Platinum Cured Silicone

Positives

Sheets and Bowie are clearer so more visibility through the material

Can be proceed talc liberated

Generally curative properties are better particularly tensible puissance and fissure firmness

Viewed as being the cleaner silicone out of the two which is why it is favoured in the Food, Beverage and Medical sectors

Negatives

More lavish than peroxide which can be prohibitive if pain is an issue

Harder to process – needs relatively exalted temperatures to coward

Short degree vivacity – once confused the compound has a very defective rotable vigor and so this most often leads to cheerless such as subdivision set above being bit etc

At Silicone Engineering we attempt both peroxide and platinum grades of silicone.The majority of silicone we become is peroxide coward silicone however for applications within the Food, Beverage and Medical sectors, we also tender platinum intensity which are favoured in these sectors.

Overall, both curing systems produce quality silicone materials if artificial to dear standards and specifications. Both have positives and indirect and which one you choose should be in recital to the poultice and where the silicone will conclusion up.
