How to dissolve rubber? Basic knowledge edition!

Dissolving rubber requires prior "kneading"!

This page introduces basic knowledge about the dissolution of rubber. General raw rubber (synthetic rubber, natural rubber) comes in a block form called a "bale," which is a rectangular solid weighing about 35 kg. If this bale is directly placed into a dissolution tank, it can cause accidents or malfunctions, so it must be processed through a "roll mill" to be stretched into a thin sheet. Our strength lies in our ability to handle both the "mixing" and "dissolution" of rubber together. We can propose improvements from the mixing process to address issues such as "the viscosity of the rubber dissolution liquid is too high (poor coating properties)" or "the quality of the rubber dissolution liquid varies." *For more details, please download the PDF or feel free to contact us.

"Are you able to clean the mixing tank?" I have estimated the amount of contamination from the previous product!

As a general statement, we verified to what extent "residual product" remains in the stirring kettle (how much "residual product" could be removed through solvent washing?) from the non-volatile content.

Objective We verified how much "previous product" remains in the stirring tank (i.e., to what extent the "previous product" can be removed by solvent cleaning) through the measurement of non-volatile components. Verification Method (Solvent Cleaning Method) Immediately after producing resin solution A (dyed purple for visualization), solvent B (2 kg of new solvent) was added to the stirring tank (50L). This mixture was stirred at 40°C for 30 minutes, after which the non-volatile component 1 of the extracted solvent B was measured. Additionally, solvent B (another 2 kg of new solvent) was added, and the above process was repeated to measure non-volatile component 2. Verification Results Non-volatile component 1 = 2.9% → Extracted 58g equivalent of previous product (solid content) through solvent cleaning Non-volatile component 2 = 0.3% → Extracted 6g equivalent of previous product (solid content) through solvent cleaning * Measurement of non-volatile components: Dry weight loss method at 120°C for 30 minutes * Non-volatile component of solvent B (new) = 0.0% Discussion - The fact that non-volatile component 2 was lower than non-volatile component 1 indicates that the effectiveness of solvent cleaning has been confirmed "to some extent." However, although the "previous product" was diluted through two rounds of solvent cleaning, it was not completely removed. * To expect a cleaning method more effective than solvent cleaning, it is considered necessary to "disassemble" the stirring tank and clean the previous product adhered to the internal blades and walls.

Dissolution processing and contract manufacturing of NBR (nitrile rubber) | OEM support

We accept solvent dissolution of NBR from 50L! We can also handle everything from rubber mixing. Through decomposition cleaning, we thoroughly prevent color changes and foreign matter contamination.

Our company offers contract processing for dissolving NBR in organic solvents, ranging from a minimum of 50L to a maximum of 3,000L. Dissolving NBR requires some expertise in handling solvents, but with years of know-how and explosion-proof stirring equipment, we produce high-quality solutions without lumps. Particularly, by thoroughly implementing "decomposition cleaning," there is no concern about contamination (previous residual mixing) even when changing colors from black to transparent or light colors. Furthermore, a significant feature of our company is that we can handle everything from "rubber mixing processing" to dissolution in one go. By providing a one-stop service from formulation mixing to dissolution, we contribute to reducing lead times and stabilizing quality. 【Features】 ■ Contract manufacturing of NBR dissolution processing starting from 50L ■ One-stop support from rubber mixing to dissolution ■ Thorough elimination of contamination during color changes through decomposition cleaning ■ Possibility of processing high-viscosity and difficult-to-dissolve NBR * Please check the document summarizing "9 Checkpoints When Choosing a Contract Dissolution Processor" available for download.

Reagent and sample aliquoting and small-scale filling services | Chuo Resin Chemical

We accept small-scale aliquoting of reagents and development samples! With clean equipment that has been thoroughly cleaned and decontaminated, we achieve precise filling that does not compromise purity.

In the promotion of new products and the small packaging of research reagents, "maintaining purity" and "handling small quantities" are extremely important. At Central Resin Chemistry, we accept sample packaging of chemical products and resin solutions starting from a minimum of 50L. Our greatest feature is our "decomposition cleaning" for each change of product type. In the world of reagents and samples where even a slight mix of previous materials can prevent accurate evaluation, our commitment to eliminating contamination through physical cleaning has earned the trust of many researchers and developers. We provide one-stop solutions from dissolving various solvents such as toluene and MEK to precise small packaging into specified containers (such as small bottles and cans). You can also rely on us for the small packaging of high-viscosity prototypes (up to 60,000 mPa·s). 【Features】 ■ Accepts small packaging of reagents and samples from small quantities ■ Maintains the highest standards of purity and quality through decomposition cleaning ■ Flexibly responds to precise filling of high-viscosity development products ■ Accelerates development speed with small-lot spot production * Please check the document summarizing "9 Checkpoints When Choosing a Contract Manufacturer for Dissolution Processing" available for download.
