Question 1

Silton은 실리콘 컴파운드에 충전제를 넣나요?

Accepted Answer

We buy the silicone base at the hardness the job needs and do not add extending filler simply to add bulk, cut cost or raise hardness. That is what we mean by "unfilled". The purchased base already contains reinforcing ingredients; application-required additives and colourants are separate.

Question 2

제 실리콘이 충전제로 경도를 높인 것이 아닌지 어떻게 알 수 있나요?

Accepted Answer

Ask us for the ash content. Compare the result with the expected ash content of the finished formulation under the same defined test conditions, accounting for reinforcing ingredients, additives and colourants. An unexpected result calls for investigation; ash content alone does not establish quality or service life. We run the test in-house on request and will state the result on your order.

Question 3

경도가 맞는데 왜 충전제 함량이 중요한가요?

Accepted Answer

Hardness is only one of the properties rubber is tested for. Changing the filler type or loading can change elongation, tear strength and compression set recovery. The full formulation and cure matter, so compare these properties under the same test conditions rather than judging by hardness or filler content alone.

Question 4

무충전 실리콘이 더 비싼가요?

Accepted Answer

Per kilogram, often yes. Per metre of finished profile, very often not. Filler is mineral and mineral is heavier than the rubber it replaces, so a filled compound is denser and a kilogram of it gives you fewer metres and fewer pieces off the same mould. Our silicone is light because we have not put anything in it to make it heavy, so the yield per kilogram is higher. A cheaper price per kilogram can still be a dearer price per metre. Service life depends on the compound and operating conditions. For extrusions we usually quote by the metre rather than by the kilogram, so you know the exact cost of what you are buying before you order.

Question 5

EPDM과 니트릴에도 해당되나요?

Accepted Answer

The same policy applies: ingredients should serve the application, rather than simply add cheap bulk. Carbon black reinforces our black EPDM and nitrile compounds, but other reinforcing systems are available for non-black compounds. Our silicone base already contains reinforcing ingredients, so "unfilled" does not mean ingredient-free.

Question 6

실리콘 고무에는 충전제가 들어 있나요?

Accepted Answer

The silicone bases we buy contain reinforcing ingredients such as silica. Here, "unfilled" means we do not add extending filler simply to add bulk, cut cost or raise hardness. It does not mean the base contains no reinforcement, or that application-required additives and colourants are excluded.

Question 7

실리콘 개스킷이 왜 딱딱해졌나요?

Accepted Answer

Heat ageing, chemical exposure, the formulation and cure can all affect a gasket in service. Loss of recovery can reduce sealing force, but it does not by itself prove that extending filler was added. Check a sample and its operating history to identify the cause.

Question 8

싼 실리콘 고무가 더 나쁜가요?

Accepted Answer

Not always, but you should know what is making it cheaper. Compare the finished cost, formulation and relevant test results under the same conditions. Price or filler content alone does not establish compression set or service life.

Question 9

충전한 고무는 왜 더 무겁나요?

Accepted Answer

Because mineral is heavier than the polymer it is replacing. A filled compound is denser, so a kilogram of it gives you fewer metres of extrusion and fewer pieces off the same mould. That is why price per kilogram and price per part often do not agree.
