How is chlorobutyl rubber stopper maintained? Anti-light: The short-wavelength part of light, especially ultraviolet light, will destroy the molecular chains inside the rubber. It is a good way to give the chlorobutyl rubber stopper a dark environment or stick a blackout material.

Oxidation, high and low temperature, light, acid and alkali oil are the main factors for the fracture of po rubber, which will cause the rubber to crack and lose its elasticity. So the maintenance of chlorobutyl rubber stopper starts from these aspects.

Rubber has a certain lifespan. Over time, it will age. In terms of storage, it needs to be placed in a cool and dry place, out of sunlight.

There are three main reasons for the stickiness of chlorobutyl rubber stopper: 1. Precipitation of small molecular components such as plasticizers (oil extenders) - one situation can be solved by adjusting the formula and storage conditions; 2. Through the formula of light-adjusting stabilizer, the surface is oxidized or degraded, avoiding light during storage and overheating; 3. Loss of release agent - treat the surface with calcium carbonate, silicon dioxide and other powders.
