06:00 AMI wake up to the chilly morning air. My day starts early but full of energy. EVAEVA is an eco-friendly material with elasticity and softness which makes it ideal to be used as soles of sneakers. Its properties of transparency, flexibility and low-temperature sealability make it an ideal material for laminating films and solar-module sheets.

02:00 PMA cup of coffee cheers me up in the middle of a hectic day. PEA polymer with outstanding physical properties and environmental stability, it is found in many different forms of plastic items we use every day. Polyethylene coating in paper cups prevent leakage.
-
06:00 PMTime to wrap up! The red taillights on congested roads tell me it’s time to go home. TDIsTDI is a feedstock for PU resin and adhesives. Flexible foams are used in shoes, furniture, automotive components, bedding, and toys, while semi-rigid foams are used in car interior materials.
-
11:00 PMTime to rest up for a fresh start tomorrow. Survived another day, good job! PVCPVC has a wide range of applications in the home, such as wallpapers, flooring materials, window frames, cable sheathing, stationary and toys.

Process Details
LDPE Process Details
-
01
Compressing
Put ethylene at gas phase in the Compressor.
Compressor
mechanical device used for compressing gas to increase pressure -
02
Reacting
Put compressed ethylene in the Reactor with Initiator.
Reactor
a device used for chemical reaction.Initiator
a substance that initiates a chemical reaction. -
03
Extruding and Separating
In this process, LDPE product is made into uniform sized-pellets.
Unreacted ethylene is recovered through a separator and reused. -
04
Packing and Shipping
Products are stored, inspected and shipped.
PVC Process Details
-
01
Polymerization
VCM, water and raw supplements are put in a reactor and heated.
-
02
Stripping
Slurry(mixture of solids and liquids) that comes out of the reactor is put into the stripping column through the top. Steam is put in the bottom of the stripping column to remove unused VCM in the slurry. The left-over VCM is reused.
-
03
Decanting and Drying
The slurry becomes dehydrated by passing through the
decanter(centrifuge). Then it is dried using hot air and water
In the dryer to become PVC resin of powdery state. -
04
Packing and Shipping
PVC resin is stored in a silo then packed and shipped.
CA Process Details
-
01
Salt Water Purification
Salt dissolved in water goes through the purification
process to remove any impurities. -
02
Electrolytic Bath
After removing impurities, salt water is put in the electrolyzer
to break down into Chlorine, Caustic Soda and Hydrogen. -
03
Transfer and Shipment
- Chlorine gas is refined and liquefied to be shipped in trucks
or becomes re-vaporized to be sent to VCM/ECH plants or
customer plants through pipes. - Caustic Soda is concentrated and stored to be shipped by
trucks or ships. - Hydrogen goes through refining process to be used as fuel or sent to customers’ plants.
- Chlorine gas is refined and liquefied to be shipped in trucks
TDI Process Details
-
01
Reaction Process
TDA and COCl2 produce TDI(main product)
and HCl(by-product) through TDA Phosgenation.TDA
substance produced by reacting Hydrogen with DNTCOCl2
substance produced by reacting Chlorine with CO -
02
By-product Separation Process
TDI and by-products produced in the reaction process are separated.
-
03
Refining Process
TAR and other light products are removed from TDI.
-
04
Shipping
Final TDI product in liquid form is stored in tanks, shipped
by tank or drums.
Polysilicon Process Details
-
01
TCS Synthesis and STC Separation
Mixed Silane gas is generated by reacting MG-Si and HCl. Through a distillation process, STC(Silicontetrachloride:SiCl4)
is separated. -
02
TCS Refining
TCS (Trichlorosilane: SiHCl3) produced in the TCS synthesis
process is refined to become pure TCS. -
03
CVD(Deposition)
Pure TCS is put into a bell-jar type reactor to decompose
at high temperature through CVD(Chemical Vapor Deposition),
and rod-shaped Polysilicon is produced. Mixed gas generated
in this process is separated by each component and reused. -
04
Crushing and Packaging
The harvested silicon rods are crushed into various forms such as chunks and chips and packed and shipped.
