"Fujiston glass beads" are beads with low distortion, high surface hardness, and chemical stability. We offer 21 types ranging from 80μ to 30mm.
We manufacture and sell glass beads for various special applications. *A size chart with product numbers according to applications is currently available.
At Bright Sign Industry Co., Ltd., we manufacture and sell various glass beads tailored for special applications, in addition to general-purpose soda-lime glass beads. We offer "Low Alkali E Beads" with an alkali content of less than 1.0%, "Pressed Beads" with minimal diameter variation within a lot due to pressing molding, and "Precision Polished Spheres" that can be manufactured with a maximum sphericity precision of 5μm through surface polishing. We also handle "Precision Particle Size Micro E Beads." 【Features】 We are a comprehensive manufacturer of industrial glass beads established as the first in Japan using the rotary kiln method. With over 50 years of accumulated technology, we can meet a wide range of requests for diameters from a few microns to 30mm. * Please refer to the PDF document for a size chart tailored to your application. * If you would like a sample, please select "Request Sample" in your inquiry.
The alkali content is surprisingly less than 1.0%! Manufacturing down to a minimum of 100 microns has been achieved. It is harder and more wear-resistant compared to regular soda-lime glass beads!
At Bright Sign Industry Co., Ltd., we manufacture and sell various glass beads tailored for special applications, in addition to general-purpose soda-lime glass beads. Glass beads down to a minimum size of 100 microns. Low-alkali beads in ultra-small perfect spherical shapes. We offer a lineup of glass beads suited for various applications. 【Features】 <Low-Alkali E Beads> ■ With an alkali content of less than 1.0%, they have high strength. Main sizes available include 212 to 355 microns and 355 to 600 microns. We also regularly supply larger E beads with diameters over 600 microns. *If you would like a sample, please select "Request Sample" in your inquiry.
The material is soda-lime glass! Suitable for standard samples/reference samples, spacer materials, and other applications.
We would like to introduce our "High-Precision Unibeads." These are spherical glass microparticles with a uniform and monodisperse particle size distribution, used as spacers for gap adjustment/control and film thickness adjustment/control. They are particularly suitable for applications that require heat resistance, load resistance, and electrical insulation. Please feel free to contact us if you have any inquiries. 【Features】 - Spherical glass microparticles with a uniform and monodisperse particle size distribution, used as spacers for gap adjustment/control and film thickness adjustment/control. - Suitable for use in applications requiring heat resistance, load resistance, and electrical insulation. *For more details, please refer to the related links or feel free to contact us.
Free samples available! Composed of strong, small glass bubbles, it reduces the weight of the target product! An additive with high compressive strength.
Hollow glass beads are advanced technology additives. They consist of strong, small glass bubbles that reduce the weight of the target product and enhance its performance. They are commonly used in FRP, GRP, plastics, adhesives, automotive applications, emulsion explosives, oil well cement, and more.
Free samples available! JIS standard compliant!! Glass beads specifically for road marking paint!!
Glass beads specifically for road marking paint ■Complies with JIS standard JIS R3301-1 and can be used in Japanese road marking paint. ■Glass beads of sizes 2 and 3 are also available upon request.
A glass bead composite with large diameter glass beads as the core and high refractive index glass beads coated on the surface.
At Bright Sign Industry Co., Ltd., we manufacture and sell various glass beads tailored for special applications, in addition to general-purpose soda-lime glass beads. Glass bead composites consist of large-diameter glass beads: those with a diameter of 0.60 to 1.00 mm (core) coated with high refractive index glass beads (refractive index of 1.9 or 2.2) on their surface. 【Features】 For road marking applications, visibility at night can be achieved even when submerged. *If you would like a sample, please select "Request Sample" in your inquiry.
As an alternative to ceramic beads! Glass beads extend the lifespan of machines and prevent over-grinding.
At Bright Sign Industry, we manufacture and sell glass beads ranging from 0.5μ to 30mm. In bead mills used for the production of paints, inks, coatings, cosmetics, pharmaceuticals, and food, ceramic beads have become mainstream. However, due to their high hardness, they can lead to machine wear and excessive grinding of powders. 【Advantages of Glass Beads】 ■ Maintains the crystalline structure of powders ■ Reduces initial costs of machinery ■ Extends the lifespan of machinery and controls running costs ■ Surface treatment (silane treatment) is possible *If you would like a sample, please select "Request Sample" in the inquiry.
A technical booklet describing glass beads and road markings. Glass beads contribute to ensuring traffic safety.
The Japan Glass Beads Association was established in 1973 by four glass bead manufacturers, and since then, it has been active in promoting traffic safety with the hope of reducing traffic accidents. This booklet has been published to help many people understand the importance of the visibility of road markings and the effectiveness of glass beads, with the hope that glass beads will be used effectively. We will continue to strive for a safer and more secure society. We sincerely hope that this booklet will contribute to traffic safety. Please feel free to download and take a look. 【Contents (excerpt)】 ■ Introduction ■ Chapter 1: Trends in Road Traffic Accidents ■ Chapter 2: Road Markings and Visibility ■ Chapter 3: Glass Beads ■ Chapter 4: Other Road Markings *For more details, please refer to the PDF document or feel free to contact us.
Translucency can be achieved! Glass beads for 3D printers that enhance heat resistance and strength.
This product is micro glass beads that align the refractive index with light-curing resin as a 3D printer molding material. By aligning the resin and refractive index, translucency can be achieved. The degree of translucency can be adjusted by changing the amount added and the ratio with other additives. Additionally, by optimizing the particle size of the glass beads, they can be evenly dispersed in the resin. 【Features】 ■ Enables translucency ■ Adjustable degree of translucency ■ Improved heat resistance and strength ■ Uniform dispersion in resin ■ Usable for temporary crowns and various connectors *For more details, please refer to the PDF document or feel free to contact us.
