Features-

 

1. Hi-pearl is a high Tg solid spherical polymethyl methacrylate (PMMA) polymer produced through suspension polymerization in water. It has a high molecular weight and is thermoplastic, offering excellent weather resistance and transparency.
2. Hi-pearl is primarily derived from methyl methacrylate and can also be copolymerized with methyl methacrylate monomers such as methyl acrylate and/or acrylic ester monomers such as butyl acrylate.
3. Hi-pearl exhibits good flowability and dispersibility in both organic and inorganic materials.
4. The polymer produced through suspension polymerization has high purity (ash content <0.01wt%), making it suitable for use as a ceramic adhesive.
5. It is soluble in various solvents and monomers.

​

Applications:

 

Hi-pearl is used in products related to displays, electronic devices, building materials, corrosion-resistant etching, paint, and ink coatings, among others.

 

Specifications-

 

• Particle size: 10 to 500 μm
• Glass transition temperature (Tg): 20 to 120°C
• Molecular weight (Mw): 10,000 to 1,000,000
• Functional groups: Carboxyl, hydroxyl, epoxy, etc.
• Biobased polymers

 

Brief Introduction to Two Product Models~

 

MA-4620 - Alkaline Development Corrosion Inhibitor Polymer~

 

• Suitable for alkaline development due to its high acid value.→Used in adhesive applications for dry film corrosion inhibitors, solder masks, and conductive pastes.
• Narrow molecular weight distribution compared to solution polymerization products, allowing for high-resolution corrosion inhibition.
• Tg, molecular weight, and acid value can be adjusted according to requirements.

​

 

​

 

M-6000 Series ~Used as an Adhesive in Ceramic Sintering ~

 

• Minimal residue during sintering, excellent moldability.
• Molecular weight can be controlled from tens of thousands to over 1,000K.
• Exhibits better thermal decomposition performance compared to cellulose and phenolic resins commonly used as ceramic adhesives.
• The M-6000 series completely decomposes below 350°C and is widely used as a ceramic adhesive.
