As a special material,high temp rubber sheet plays a significant role in many industrial fields.Many people have this question:Is it afraid of water?To answer this question,we need to comprehensively analyze it from aspects such as its material properties,production process,and actual application scenarios.
From the perspective of material composition,the main components of high temp rubber sheet are usually nitrile rubber or other synthetic rubbers,and various additives are added to enhance its performance.This special formula design makes it less likely to absorb water and expand or deteriorate like ordinary rubber when exposed to water.
In terms of production process,the raw material ratio and processing conditions are strictly controlled during manufacturing to ensure the uniformity and density of the internal structure of the product.As a result,even if it comes into contact with water,it is not easy for water to penetrate.At the same time,some high-quality high temp rubber sheets will undergo surface treatment,such as applying a waterproof coating,to further enhance their waterproof performance.These measures effectively reduce the impact of water on their performance.

Although high temp rubber sheet has a certain waterproof ability,this does not mean that it can completely ignore the existence of water.
In actual use,if it is immersed in water for a long time or exposed to a humid environment,it may still be affected to some extent.For example,long-term water immersion may cause changes in the spacing between rubber molecular chains,thereby affecting its elasticity and mechanical strength.In addition,impurities and chemical substances in water may also react with rubber,accelerating the aging process.Therefore,in some special working conditions,such as underwater operations or high-humidity environments,additional protective measures need to be taken.
The waterproof requirements for high temp rubber sheet vary in different application scenarios.
In the petrochemical industry,it is often used as sealing parts,gaskets,etc.,and at this time,the focus is on its sealing performance and corrosion resistance at high temperatures,while the waterproof requirement is relatively low.However,in some outdoor facilities or water conservancy projects,a higher waterproof grade is required.For example,the high temp rubber sheet used in bridge bearings not only needs to withstand huge pressure but also needs to withstand the test of rainwater erosion and groundwater erosion.In such cases,products with better waterproof performance will be selected,and reasonable design and installation methods will be adopted to ensure their long-term stable operation.
To extend the service life of high temp rubber sheet,correct maintenance and management are crucial.
In daily use,it should be avoided from being directly exposed to a large amount of water,especially when not in use,it is best to store it in a dry and ventilated place.If it is inevitable to come into contact with water,it should be dried in time after use and regularly inspected.Once any damage or abnormal conditions are found,it should be replaced in time.At the same time,for rubber sheets that are in a humid environment for a long time,it is advisable to consider adding protective covers or other moisture-proof facilities to reduce the impact of water.
High-temperature resistant rubber sheet is not completely waterproof,but through special material selection,fine production processes,and reasonable application and maintenance methods,it has good waterproof performance.In different application scenarios,as long as suitable products are selected according to actual needs and appropriate protective measures are taken,its advantages can be fully utilized to ensure the safety and stable operation of equipment.
