  h) Fabric for FRP, woven roving(COMPOSITE REINFORCEMENT FABRICS) :
                              wind surfing board, Molding porducts.

  i) fabric for Flame Retardent glassfiber Tape.
  You Chang  glass tape possesses properties of non-combustible and has characteristics of heat-resistant. 
  It can be applied for industrial use, shipbuilding field, and duct construction for buildings.

  Part No :  YC-312-36
  Spec    :      Yarn : ECG 75 1/0     Density : Warp 18,  Weft : 18,   Weight : 96g/m2
                     Al-foil : 7u.   Adhesive :Acrylic Resin,  Hot Melt Resin
  Available Size : 50mm x 50 m/R ,   75mm x 50 m/R,   100mmx 50m/R
 
H) Long Fiber Reinforced Thermalplastics for tooling housing
 is produced with Roving that consist of thousands of filaments(Diameter is 10~20 pmm) 
  a) Higher mechanical properties
  b) Espacially higher notched impact strength
  c) Increasing endurance because of reduction of creep tendency 
      and the increase of fluctuating fatigue strength
  d) Cost-down by using of master batch( You can control contents of fiber)

   Applications : 
   Auto parts, Engineering, Civile, Housing & Office, Sports gods, Toy, Ship&Airplain parts, Railing.

I) Basalt Fabric : 355g/m2 is almost the same appearance as 3K carbon fabric  200g/m2.
355g/m2 samples are availabe right now.    The spec are  Yarn (300 Tex), Density (15 * 15).
 Basalt fibers are new unique and economic products with superior properties 
to similar one in present use like as glass fibers. 
In thermal conductivity, articles made of basalt fibers are 3 times as efficient 
as those made of asbestos, and superior to glass and mineral fibers. The 
application temperature of articles made of basalt fibers markedly higher (from 
-260 ”ĘC to 900 ”ĘC). 
In their physical properties (strength, elasticity) basalt fibers considerably exceed mineral and glass fibers.
Due the elasticity of micro- and macrostructure, basalt fibers are vibration-resistant compared to similar 
products. This property is of particular importance in mechanical construction and civil engineering. For 
example, when buildings are erected near highways, railways and underground, whereas under vibration 
cushions of mineral and glass fibers experience damage and finally disintegrate, basalt slabs are 
vibration-resistant and, hence, more durable. 

This will be last trial, In the near future, we can not collect anymore again
as we promised to our local dealers.
In chemical properties basalt fibers are more resistant to aggressive media i. e. acids and alkalis. Therefore 
pipes made of basalt fibers may be used in the chemical production for transporting hot acids, in the 
construction of sewerage systems, transportation of aggressive liquids and gases, loose materials, etc. 
Dielectric properties of basalt-plastics, in particular volume resistance of basalt fibers are 1 to 2 orders of 
magnitude higher than those of fiberglass. 
Basalt fibers can be used in various branches of industry fully replacing cancerous asbestos and to a 
considerable degree glass fibers and metals. 
The processing technologies of basalt fiber conforms to traditional technologies of glass fiber processing 
(fabrics, roving, chopped strands, GFRP). Thanks to their excellent properties basalt fiber may be used for 
manufacturing of thermo and alkali resistant articles (tanks, pipes, GFRP, warm insulating materials) and as 
ecological harmless substitute for asbestos. 

We'll be very appreciated if you give us a chance to serve you
We look forward to getting your future requests, and remain.
Very truly yours
