19 I would like to have your table of physical properties.
reply

Please visit our website and refer to Product and Service > Resin Products category. You can query and print the table of physical properties for each product.

18 (Other) What are the directions for handling and storing MMM products?
reply

They should be kept in airtight containers and stored in cool, well-ventilated place to avoid heat, light, and direct sunlight. Be cautious when opening and closing the container to avoid causing sparks, use the required equipment and wear protective gear for handling. For more details, please refer to MSDS.

17 (Other) I would like to buy your EG products. What should I do?
reply

Thank you for your interest in our products. Please give us a call using the number for appropriate department in Customer Inquiry menu, and we will let you know the details.

16 (Other) How can I obtain MSDS data on EG?
reply

Please refer to the application section for Technical Support / Authentication Certificate Issuance under Product/Service on our website.

15 (Other) What kind of products are produced in the petrochemical plant?

I would like to know about the physical properties and characteristics of EO.
Thank you for your interest in our products. Please use the technical data section.

14 (Other) What does the term NCC mean as used in the petrochemical plant?
reply

NCC is an acronym for Naphtha Cracking Center, generally meaning an ethylene plant that produces the main products of ethylene and propylene through pyrolyzing naphtha, created in the refinement process of imported crude oil at a refinery , as its raw material at ultra-high temperature of 810 ~ 870℃ and byproducts such as hydrogen, methane, C4 fraction, PG, C3/C4LPS, etc.

13 (PET) What do PET or PETE on PET bottles indicate?
reply

PET bottles are molded in polymer material called polyethylene terephthalate.
At the time of recycling, abbreviations are shown on the containers for easier segregation. PET or PETE means Polyethylene Terephthalate.
Polyester fibers used in making clothes are also made from the same material as PET bottles. Like this, the very same polymer materials can be made into various other products depending on the molding methods.

12 What is (functional resin) HMS-PP?
reply

With its linear molecular structure, the existing PP makes it impossible to perform high- magnification extrusion foaming and large thermo-foaming due to the rapid drop in viscosity and melt tension when melting.
High Melt Tension Polypropylene (HMS-PP) is a product with improved melt tension and viscosity with the introduction of Long Chain Branching (LCB) by polymerizing the existing PP or subjecting it to post-treatment.
It is widely used in high-magnification extrusion foaming, large vacuum and pressure molding, high-speed coating, etc., which have been hitherto difficult to mold with the existing PP.

11 (Functional resin) What kind of functional resins are produced by LOTTE CHEMICAL?
reply

PE and PP are widely used as general-purpose resins for their low price, excellent mechanical and chemical properties, and processability. However, they have the disadvantage of non-compatibility with polar materials due to their stable non-polar structures consisting of only carbon and hydrogen.
It is adhesive polyolefin resin that renders adhesiveness to non-polar polyolefin by chemically introducing polarity to it.
The polyolefin modified by the functional group with adhesive function has the characteristics of adhering to various kinds of materials and retaining the excellent physical properties of polyolefin as they are by introducing the polar group in side chains rather than in the main chains.

10 (Functional resin) What is the difference between Lottmer H-Series and S-Series?
reply

Thermoplastic elastomers are broadly classified into 5 groups according to their basic material: olefin-based, styrene-based, PVC-based, engineering plastic-based, and super TPV. The basic material for each is as follows:
Two product groups are produced out of the five groups. The Lottmer H-Series is olefin-based thermoplastic elastomer, whereas the Lottmer S-Series is styrene-based.
