Part I. TPE Introduction
1. Standard definition of TPE
According to ISO 1382, Thermoplastic Elastomer is a polymer or a
mixture of polymers which doesn’t need vulcanisation or reticulation
when processed, but demonstrates similar properties as vulcanised
rubber at service temperature. These properties disappear at processing
temperature to allow the ulterior process possible, but reappear as the
material returns to working temperature.

4. Conception of base of TPE
Principle: In all the TPEs, it exists one soft phase and one
rigid phase, which endow the material with elasticity.
Example 1: SEBS and SBS
Rigid phase:
Polystyrene
Soft phase:

 Because of the existence of vulcanised rubber, TPV is generally difficult to process, and TPO,
which has a property very close to thermoplastic, can be processed very easily. The
processing facility of other TPE is between the two.

Part II. Multiflex Introduction
1. What is Multiflex ?
Multiflex are compounded thermoplastic elastomers based on
different polymers, like SBS, SEBS, Polyolefins and other engineering
plastics. They are totally different from pure SEBS or SBS.
That means all of Multiflex products are Compounds and our
producing art is Compounding.

Part II. Multiflex Introduction
2. What is compounding ?
To mix one base polymer with certain other materials like oils,
fillers, additives and other polymers, in order to give some properties
to the mixture, so that it can be used for the final application.
The final mixture is called compound.

 Important points: compared to
toothbrush grips, this application
has always more mechanical
requirements, which leads to the
use of more engineering plastics,
like PA and ABS. . .

3. Application in development
-- To enlarge our sight
 Flooring application:
 In Europe and U.S.A, “No PVC” is rather an action than a slogan, certain flooring
producers has already engaged in looking for “environment friendly” substitute.
 This application includes boat deck, hotel floor, and even supermarket floor!
 Flame Retardance without halogen, which is quite difficult for a normal TPE-s to
achieve, is the biggest handicap in this development project.
 Certain Multiflex samples has already met the requirement, but unfortunately, the raw
material supplier stops its supplying.
 Some new material will be tested soon.
 Economy is a very important condition for this application.

 Interior seal whisky bottle cap application:
 Huge volume of whisky and cognac is exported to East Asia every year, especially to
Taiwan and Hongkong.
 “No seeping” is very important during the transportation.
 No odor, food approval, good C,S and excellent injectability(multi-caves) are the most
important conditions for this application.
 Considerable potential is behind this application.

 SBS product range:
 SEBS product has no competive advantage compared to TPV.
 SBS is accepted in more and more applications, where no special requirements exist, like
UV stability, Exellent C,S, or very special soft touch. . .
 Nowdays, our most aggressive competitor in Europe is TCT, who focus his developing
ability on SBS product.
 Multibase is now working for enlarging its SBS(C) product range, to meet the demand of
market, especially for Asia.
