Silicone. Silicone is a good substitute for rubber. It is man-made material that is typically inert, contains low toxicity levels and is largely heat-resistant. For these reasons and due to its rubber-like texture, its often used in cookware as well as in lubricant and adhesive materials.
What is a material like rubber?
Characteristics of elastomer materials Elastomers or rubber-like materials have been used as an engineering material for nearly 150 years. The term elastomer, which is derived from elastic polymer, is a polymer which has the property of viscoelasticity, with low Youngs modulus and high yield strain.
Which substance is used as a substitute for natural rubber?
In all other respects, though, isoprene rubber is a complete substitute for natural rubber. For both materials, the principal usage is in tires, although these elastomers are also preferred for rubber springs and mountings, owing to their good fatigue resistance and high resilience.
Can natural rubber be replaced?
Synthetic (man-made) rubber can be produced through a chemical process, but people have not been able to produce a synthetic rubber that has all the properties of natural rubber. So, natural rubber cannot be replaced by synthetic rubber in most of its applications.
What are the three types of rubber?
Types of RubberNeoprene Rubber. Neoprene rubber—also called chloroprene—is one of the oldest types of synthetic rubber. Silicone Rubber. Nitrile Rubber. EPDM Rubber. Styrene-Butadiene Rubber (SBR) Butyl Rubber. Fluorosilicone Rubber.29 Jul 2020
Which is better silicone or rubber?

For high temperature applications, silicone is certainly the better choice....Silicone vs Natural Rubber.Natural RubberSiliconeApprox. tensile strength 25 MPaApprox. tensile strength 5 MPaExcellent abrasion resistancePoor abrasion resistance5 more rows•13 Nov 2017
What are the examples of natural rubber?

What is natural rubber example?
1. The polymers that have elastic character like rubber are called as elastomers. 2. Example : Neoprene , Vulcanized rubber, etc.
Why is natural rubber better than synthetic?
An advantage natural rubber has over synthetic rubber is that natural rubber has higher tensile strength, higher tear resistance, and low odor compared to IR. In addition, synthetic rubbers can have excellent heat resistance, lower temperature resistance, and heat aging improvements.
Is natural rubber cheaper?
Is Synthetic Rubber Better than Natural Rubber? Synthetic rubber also tends to be cheaper to produce. On the other hand, natural rubber is known for its properties as a strong, flexible and heat-resistant material used to create latex products. Ultimately, which type of rubber is better depends on its application.
What is the cheapest type of rubber?
Styrene Butadiene Rubber Styrene Butadiene Rubber (SBR) is one of the cheaper general purpose rubbers.
Is natural rubber better than silicone?
Silicone has relatively low abrasion resistance, and in applications where a part will be subjected to abrasion and wear, natural rubber is a better choice. Silicone has excellent resistance to weathering and UV, and is often found in outdoor applications such as door and window seals.
Where is natural rubber used?
Natural rubber, or latex is used mostly in car tyres and medical products. Vulcanised rubber is mainly used to produce automotive tyres, however there are a large number of additional applications, including seals and medical products (e.g. surgical gloves).
What are the applications of natural rubber?
What is Natural Rubber Used for? Natural rubber is used in applications requiring a high level of wear and heat resistance. Thanks to its strength and compressibility, natural rubber is used in engineering applications, like anti-vibration mounts, drive couplings, springs, bearings, rubber bands, and adhesives.
What are the disadvantages of synthetic rubber?
Though synthetic rubber has innumerable advantages but its disadvantages are no less. ◼It has poor mechanical properties . ◼Its tensile strength is quite weak. ◼Tear strength is also very poor.
