PASCON is a new material that can be reproduced repeatedly by melting waste thermoplastics and combining it with fly-ash (a by-product of anthracite generated in a thermo electric power plant) and blast -furnace slag (a by-product of iron ore melting in a steel mill). The most recently developed ESSCON is a new Eco-friendly flame retarding material, which can be used on products requiring nontoxic flame-retarding performance, made by adding inorganic flame retardant developed by ourselves and other reinforcing materials. The two materials are both manufactured and produced by 1,000 Ton capacity large size injection machines.
The fluidity of the raw material is very low due to the density in melting state and presence of many impurities. In addition, the fly-ash and furnace slag have respective hardness and sizes. Hence, the manufacturing of the new material PASCON requires astute technical knowhow in the reprocessing facility which can keep constant granularity through crush and screening while maintaining smooth injection. There were many technical problems such as the reduction of mold’s lifespan by enlargement due to basic hardness of the raw material. Nevertheless, we overcame these problems with consistent investment and continuous R&D and succeeded in obtaining the substance patent, and subsequently we were able to promote the commercialization of various products as we now see.
Background of development / Properties
| Background of development | Properties |
|---|---|
| Weakness of concrete trough by certain factors (vibration, ultraviolet, acid fallout, sea water, deicing agent, modifiability ) and need additional device for installation /removal due to its heavy weight | Manual installation/removal with light weight (1/5) Durability for more than 20 years Definite reduction of construction cost and period Excellence of chemical resistance Satisfaction of Euro standard for strength (EN 124 - A15 for Trough) Suitable to use evacuation passage in emergency Easy to adapt during installation |
| Low recycling rate for plastic and fly-ash,slag compared to their generation and makes environmental problems due to land reclamation by them | Contributing to increase of recycling rate by using recycled plastics and fly-ash ,slag |
| Exhaustion of natural resource like aggregate and consequential environmental contamination. cost increment of treatment and reclamation for industrial /construction waste |
Save natural resources and preventing environmental contamination Save cost of treatment and reclamation for industrial / construction waste |

- 1. Act Concerning Purchasing Promotion for green products [Enforcement on 31/3/2014][Act. No. 12140, partly revised on 30/12/2013]
Article 6 (Duty of public institutions to purchase green products) Head of public institutions should purchase green products when it is necessary to purchase products, except in the case of each number below. - 1. In case of no green product in the list of products to buy
- 2. In case of unstable supply of green products
- 3. In the case that purpose of purchase is hardly achieved due to substantial degradation of quality on green products
- 4. In case of purchasing products other than green products to comply with preferential purchasing regulations defined in other laws like Welfare Act for Disabled Persons
- 5. In the case that head of the public institution decide to purchase other than green products due to unavoidable reasons such as urgent demand
Now, PASCON not only has the economic and environmental propagation effect in a nation but is also receiving favourable comments from the EAST ASIA PASCON NETWORK PROJECT including Japan, China and railroad industries and numerous construction sites in America. Hence necessity of its use will grow constantly to maximum. Also, it will contribute greatly to expansion of green policy worldwide. Please contact us for further information without hesitation.
