Types of Natural Rubber (NR)

Natural rubber (NR) is an elastic solid produced by processing a milky sap collected from specific plants. Its main component is polyisoprene, a polymer structure that endows it with unparalleled high elasticity, flexibility, and resistance to fatigue.

Properties of Natural Rubber and Its Main Production Areas

I. Advantages of Natural Rubber: 1. High Elasticity: It features a high rebound rate, low hysteresis loss, and low heat generation. 2. High Strength: The tensile strength of pure rubber vulcanizates can reach 17–25 MPa; after reinforcement with carbon black, it can increase to 25–35 MPa. It also exhibits excellent fatigue resistance and flexural endurance. 3. Good Processability: After plasticizing, it has high plasticity, making it easy to mix, calender, and extrude. 4. Excellent Adhesion: It bonds easily with other materials.

Repost: Two-stage (baking) vulcanization of silicone rubber

After a first-stage vulcanization, since the temperature (150℃) is relatively low, some low-molecular-weight substances still remain in the vulcanized rubber, thereby affecting the product’s performance. For example, in silicone rubbers vulcanized with BP or DCBP, the acidic substances—such as benzoic acid—that are generated from the decomposition of the vulcanizing agent remain in the vulcanized rubber after the first-stage vulcanization. When the product is used under high-temperature, sealed conditions above 200℃, these substances cause cracking, leading to a significant drop in hardness and a sharp deterioration in physical and mechanical properties, ultimately rendering the product unusable. To address this issue, a second-stage vulcanization is required to remove various low-molecular-weight substances from the rubber. Moreover, the second-stage vulcanization can also eliminate moisture or crystal water from fillers, thereby preventing hydrolytic aging of silicone rubber products during use or storage.

A Product Engineer’s Daily Routine: Striking a Balance Between Drawings, On-Site Work, and Communication

A product engineer’s day typically begins with checking emails and reviewing project progress. For product engineers at manufacturing companies that produce automotive parts, consumer electronics, and other products, the top priority is to thoroughly understand the product drawings, data, and technical standards provided by customers.
