Does foam caulk also expand with heat and shrink with cold?

Foam caulkis a Polyurethane foam adhesive material with a wide range of uses. Polyurethane foam caulking agent is mainly used to fill gaps in building doors and windows, and can also be used In cold storage, air conditioning, electronics industry, solar energy and automobile manufacturing. High-quality foam caulking agent After curingIt can effectively fill gaps, waterproof and leak-proof, does not shrink or deform, and is green, environmentally friendly and pollution-free.

1、Foam caulkWill there be thermal expansion and contraction after curing?

After curing, polyurethane foam caulking font>presents a low-density foam-like material. The hardness of this material depends on the raw material, and different fields have different requirements for hardness. By cuttingfoam caulk, you can observeFoam caulk is composed of many foam voids, which has good adhesion to the substrate, thereby achieving waterproof sealing‘s effect. Under normal circumstances, under certain temperature conditions, the cured foam Caulking agentwill not expand with heat or shrink with coldphenomenon. If the temperature is below zero20degrees, or above zero120 The degree may affect the normal use and performance of the foam caulking agent.

Want to knowFoam caulk After curing, thermal expansion and contraction occur, so you need to knowFoam caulkTemperature resistance after curing. High quality‘s Foam caulkFrom Zero20 Degree Zero Above120will not shrink or become brittle. After curing, the volume expands many times, but the weight does not increase. It can be used for Door and window installation andAutomotive ManufacturingEffective filling.

2、What kind ofFoam caulkIs it good?

BuyPolyurethane foam caulking agentBe careful when using . While paying attention to price, you should also pay attention to performance. If the performance is poor, you cannot exercises the expected effect of the product but fails to meet the usage requirements. After curing, it should be very good Thermal insulation, waterproof, moisture-proof, Caulking and bondingPerformance is the bestYes, but cannot be posted The soft strength should be high. Especially when used on doors, windows and cars, you should pay more attention, after all, it may Affects the safety of our lives and property.

Foam caulkingis widely used and its applicationIn addition to traditional door and window caulking, many other fields also has long been involved, The authors will not be listed one by one. Therefore Foam caulkThe quality is crucial , does not release volatility after curing Gas, no Can contain formaldehyde, CaCan be applied toVarious fields.
