The whitening (frosting) issue in rubber products is a complex, multifactorial problem that involves rubber materials science, processing technology, and chemical-physical changes, among others. To better understand and solve this issue, it is necessary to explore the following areas: the microscopi

EPDM (Ethylene Propylene Diene Monomer) is a commonly used elastomer material known for its excellent weather resistance, ozone resistance, heat resistance, and aging resistance. It is widely used in industries like automotive, construction, and electronics. However, despite its superior properties,

Silicone rubber is a synthetic rubber elastomer that is frequently used for many applications across many different industries. Silicone is different from silicon: silicon is an element, while silicone is a polymer that contains silicon, among many other elements. There are different variations of t

Silicone products are gaining popularity due to their environmental friendliness, and there's an increasing trend of using silicone in various items. To understand these products systematically, let's start by exploring the basics of silicone raw materials.Classification by Performance:Color: Transp

I. Definitions of Hardness and Elasticity:Hardness refers to the surface resistance to indentation of an object, usually measured using hardness testers such as Shore A, Shore D, or IRHD. Elasticity is the ability of an object to regain its original shape after deformation, indicating its ability to

Natural Rubber (NR):Appearance: Pale yellow and semi-transparent.Burning Characteristics: Burns easily.Flame Characteristics: Produces black smoke, a dark yellow flame, and becomes soft.Residue Odor: Smells like rubber with non-sticky residue.Isoprene Rubber (IR):Appearance: Pale yellow and semi-tra

Rubber damping products are generally referred to as rubber dampers. There are many types of rubber dampers, and they can be categorized based on the type of vibration force they endure, such as compression, shear, torsion, impact, and hybrid types. With the advancement of technology, the types of r

Classification and Structure of Rubber MoldsWith the development of China's rubber product industry, the variety and production volume of rubber products have been increasing, driving the shift from traditional empirical design to theoretical calculation design for rubber mold design and manufacturi

The difference between recycled rubber and recycled plasticRegenerated rubber and recycled plastics are the two most commonly used renewable resources in the product industry at present. Among them, recycled rubber is processed from waste rubber products and rubber product corner waste as raw materi

Methods for Determining Plasticity:Compression Method:This method includes the Williams method, the Wallace Rapid Plasticity method, and the De Mattia Plasticity method. These methods measure the plasticity of raw rubber and compounded rubber and are conducted at a constant temperature since plastic
