JIURI New Materials, established in 1998, is a Chinese manufacturer with more than 20 years of industry experience, and a valued partner of Aalchem since 2012. Focusing primarily on Photoinitiators, JIURI serves 1,200+ customers around the world in a variety of industries, including:

·         Optical Fiber Coatings

The JIURI Group currently has three production bases in three different provinces and thereby in three independent industrial parks.  There is a fourth production base actively under construction.  Jiuri intentionally creates redundancy by manufacturing several of their products at more than one location. With their current three production bases, JIURI is able to offer an annual capacity of 25,000 metric tons.

This redundancy in manufacturing ensures supply and allows Aalchem to keep stock throughout the United States, making for a faster turnaround time on your orders. We have the following JIURI products currently stocked in these states:

Michigan: 1109, 1173, 184, 379, 4265, 500, 910, BDK, DETX, EDB, EHA, EMK, ITX, MBF, MBP, OMBB, PBZ, TPO, TPO-L

South Carolina: 1173, 184, 500, 907, OMBB, TPO

 Illinois: 1041, 184, 500, 910, MBP, PBZ, TPO

JIURI strives to be environmentally conscious in their manufacturing, responding to rising trends of domestic environmental policy by implementing higher production standards in their HUNAN JIURI location.

With a focus on technological advances, JIURI New Materials is constantly increasing their investments in R&D and modern scientific administration. Their R&D team is led by 3 doctors and 28 holders of master’s degrees in organic chemistry, and they have several professors from Nankai University consulting their team. JIURI’s production plants are compliant under the ISO 9001:2008 quality management system, and the majority of their photoinitiators have been registered with REACH, including 1173, 184, TPO, TPO-L, 369, 907, BDK, DETX, ITX, and OMBB. In addition, they have applied for 76 Chinese patents, 43 of which they have been granted.

JIURI New Materials is dedicated to strict quality control in all aspects of production to guarantee the highest quality in their products, operating through global marketing and service networks to provide the best possible customer service.

If you have any questions about JIURI New Materials, or are interested in technical information, samples, or pricing please submit a request online or contact us at info@aalchem.com.

JIURI New Material has been the most stable supplier of more than 20 photoinitiators over the past 20 years adding redundant manufacturing facilities and securing multiple raw material suppliers. 

Photoinitiators: Curing with Light and Confidence

Photoinitiators are useful compounds that when added to a formulation convert light energy into chemical energy. Photoinitiators are widely used in adhesives and sealants, powder coatings, wood coatings, clear coatings, pigment coatings, composites and inks. When photoinitiators absorb light they produce reactive species that are able to initiate or catalyze chemical reactions. These chemical reactions can be used to change solubility or other physical properties.

The process of photoinitiators absorbing light and turning a liquid into a solid is called Radiation Curing. This creates a chemically and physically resistant coating that is formed by an insoluble crosslinked polymer network. This process is initiated using either UV/EB curing or LED curing. Benefits of radiation curing include:

The two most common types of photoinitiators are Free Radicals and Cationic. 

Free Radicals are the most widely used photoinitiators and have a strongly developed product line with many different applications. Free Radicals are usually used within styrene-based or acrylate-based formulations for polymerization.

Free Radical Photoinitiators can be divided into two classes.

Type I: Photoinitiators experience a unimolecular bond cleavage to make free radicals. Includes:

Type II: Photoinitiators experience a bimolecular reaction to make free radicals. Includes:

Cationic are often used for formulations with epoxy or certain resins. When a cationic photoinitiator absorbs UV light it is converted into either a Lewis or Bronsted acid which begins the polymerization.  Cationic photoinitiators can continue curing after being exposed to the light and is unaffected by oxygen. This allows for highly efficient curing times and can be an advantage over free radicals during the photopolymerization process. Using cationic photoinitiators for epoxy coatings typically provides strong adhesion, high gloss, clarity, and resistance to chemicals and abrasion.

Cationic photoinitiators are widely used in printing Ink and overprint varnishes such as can coating, industrial metal coating, coil coating, packaging, glass hard coat, optical fiber coating, nail coating. Cationic photoinitiators are ideally suited for these coatings due to their low shrinkage after polymerization, superior adhesion, high chemical resistance and no oxygen inhibition.

Photoinitiators offer a lot of advantages to the curing and formulation processes. Their versatility of attributes and applications make them highly useful products. Aal Chem has well developed supply chains, and can offer competitive pricing with strong technical assistance.
