Color

It is generally waterwhite, less than 50 on the APHA color scale. It remains very stable even when exposed to ultraviolet radiation, and its color is also more stable than that of mineral oil of the same APHA Color.

Viscosity

It is self-adhesive, and the viscosity increases as molecular weight and viscosity increase.

Purity and Toxicity

It is known for its high purity with extremely low chlorine and sulfur content and non-toxicity by not using additives

Stability

It shows excellent stability against heat and UV radiation.

Oxidation stability

Its excellent oxidation stability leads to good resistance to light and heat during use in ordinary conditions.

Lubricity

As there is no carbon residue at high temperature and it has a high viscosity index, it can be used in blends with other lubricants, oils, etc.

Viscosity

The viscosity varies from 10 to 5000 Cst when measured with a Cannon-Fensky capillary viscometer at 100 ° C. As the molecular weight increases, the viscosity increases.

- The change in viscosity with varying temperature can be predicted on the basis of ASTM D341 as follows.log log(ν+0.7)=A-BlogT ν: kinematic viscosity / A,B : Coefficient / Temperature, K

The change in viscosity with varying temperature - When blending Daelim Polybutene with different viscosity, you can obtain products with the desired viscosity. The following formula can be used to roughly calculate the viscosity according to the composition ratio of each grade. Inν= X1Inv1 + X2Inν2-BlogT ν: kinematic viscosity of the blend / v1: kinematic viscosity of the 1st component / ν2; kinematic viscosity of the 2nd component
X1: weight fraction of the 1st component / X2 : weight fraction of the 2nd component

- Molecular weight : Its average molecular weight (Mn) ranges from 300 to 2,500, determined by Gel Permeation Chromatography (GPC).

GRNERAL GRADE @ TYPICAL VALUE

Daelim Polybutene was granted the KT mark for new localized technology and the Ministry of Science & Technology and the Korea
Industrial Technology Promotion Association in November 1994. The company also received the IR52 Chang Young-sil Award for Technological excellence in 1995.

FUEL and LUBRICANT ADDITIVES/LUBRICANTS V

The double bond per molecule allows the production of fuel detergent, lubricant dispersant, etc. through chemical reaction.

- Fuel detergent additive reduces deposits on engine valves, fuel injectors, pistons, carburetors and combustion chambers, and decreases exhaust emissions, prolonging the lifetime of the engine.
- Lubricant dispersants minimize engine deposits formed due to a lack of engine priming from sudden acceleration. Those in commercial use are prepared using polybutene.

LUBRICANTS

- Two-Stroke Engine Oil

Two-stroke engines are used in scooters, lawn mowers, chainsaws and boats. Adding Daelim Polybutene reduces smoke in the engine exhaust system at high temperature.

- Lubricant for Rolling and Wire Drawing

Unlike mineral oil, Daelim Polybutene leaves almost no carbon residue in rolling operation and wire drawing involving aluminum and copper. It is environmentally friendly, helping to solve pollution problems.

- Compressor Oil

Daelim Polybutene is free of sulfur and other impurities, which removes the danger of catalytic poison and other problems.

- Viscosity Index Improvers

A viscosity index improver with Daelim Polybutene added minimizes changes in lubricant oil viscosity affected by temperature.

ADHESIVES

Daelim Polybutene is used for wide applications in the formulation of various types of adhesives.

- Pressure Sensitive Adhesive(PSA)

Raw material

- Base polymer : natural rubber, SIS, SBR, PIB, etc.
- Adhesives : hydrocarbon resin, rosin, polybutene, etc.
- Others : filler, antioxidant, solvent, etc.
- Polybutene improves the tack and peel strength of elastomers. The major applications of PSA are general and insulation tapes.

- Hot Melt Adhesive(HMA)

Raw material

- Base polymer : EVA, SBS, SIS, APP, PE, etc.
- Adhesives : hydrocarbon resin, polybutene, etc.
- Others : paraffin wax, filler, antioxidant, etc.
Daelim Polybutene increases the melt index (MI) and provides flexibility at low temperatures. It is very compatible with SBS, SEBS, SIS, and PE. The major applications of HMA include packaging, book binding, and disposables such as diapers.

CAULK and SEALANT

Daelim Polybutene is used for caulk and sealants as a Adhesives and plasticizer with excellent non-drying UV stability and viscosity. The main uses of caulk and sealants with Daelim Polybutene are for construction, automobiles, shipbuilding and refrigerators.

Daelim Polybutene meets the standards regulation designated by the Korea Food Additives Board, and it is currently used as a base material for chewing gum and bubblegum.

Adding 1~6% Polybutene to LLDPE improves film properties including elongation, tear resistance, impact strength, viscosity and low temperature flexibility. Its main applications include industrial stretch film and wrap film.

Daelim Polybutene is mainly used in electrical applications, such as jelly compound due to excellent electrical properties from a lack impurities.

Cable Jelly Compound

Its great heat stability, waterproofing property and low power factor is appropriate for use as a petroleum jelly compound.

Insulation Oil for Condensers

It is used as insulation oil for low voltage condensers because of its outstanding electrical properties, heat stability and oxidation stability.

Asphalt Modifier

Enhances low temperature flexibility, waterproof property, and viscosity when used in asphalt sheet.
