Dissolvable Rubber https://www.eastnewmaterial.com/Dissolvable-Rubbers.html Our company's WS soluble series is divided into five grades according to different melting temperatures: WS30, WS40, WS50, WS60, WS70, WS90, WS130, and WS140. The specific properties are as follows: The sol cartridges are divided into compression type and expansion type, which are used in unconventional oil and gas fields, multi-stage perforated bridge plug completions, ultra-deep wells, remote development wells, and depleted reservoirs. The rubber cartridge can be dissolved in clear water at a certain temperature, and the higher the temperature, the faster the dissolution rate, which fills the blank of domestic soluble rubber cartridges and reduces production costs.
