LF resins are used in inks, coatings, adhesives, rubber, concrete
curing and foundry applications.
Aromatic, chemically inert, and non-saponifiable C9 resins,
promoting filler wetting and viscosity control, along with tack
and adhesion; in adhesives (suitable for solventbased, pressuresensitive
and hot-melt adhesives) and caulks to improve
tack and bond strength; and in rubber compounds as a processing
aid.
Diisononyl-Phthalate and Diisodecyl-Phthalat are high molecular
weight standard plasticizers on phthalate basis; DINP
and DIDP are applied to improve the processibility of NR, bR,
SbR, NbR, CR, ECO, ACM and AEM. Due to the branching of
the alcohol chains DINP and DIDP provide a high migration
resistance und a low volatility.
Diisoundecyl-Phthalate is a high molecular weight special
plasticizer on phthalate basis. Due to its low fogging values
and high migration resistance DIUP is used in automotive applications,
e.g. car interior. DIUP can be applied in NR, bR,
SbR, NbR, CR, ECO, ACM and AEM.
Ditridecyl-Phthalate is a very high molecular weight special
plasticizer on phthalate basis. Due to its very high molecular
weight und the outstanding low volatility DTDP is recommended
for high temperature applications, such as high-voltage
cables and for parts inside or close to the engine.
Paganini Oils (370P – 4500P) are paraffinic Group I oils (processing
oils) without labeling obligation and a high content of
aromatic hydrocarbons. The main applications are in the rubber,
paint and plastic industry. benefits: low ash content, low
aniline point, low asphalt content and a low loss of vaporization.
Puccini Oils (4P – 475P) are paraffinic Group I oils (processing
oils) with the main application in the rubber and printing inks
industry. benefits: Core cuts with low sulphur contents
(< 0,3%), color fastness, bright color, minimal vaporization
loss when heated, low contents of aromatics and good oxidation
stability.

Styrene-butadiene-Rubber (SbR) is the most widely used
synthetic rubber and is applicable in many different fields.
It is primarily used for the production of tires, flooring, conveyor
belts, shoe soles, seals and and has a good heat stability,
abrasion and ageing resistance.
Solution SbR (S-SbR) is mainly used for treads of environmentally
friendly tires (Green Tire). S-SbR in combination with
silica reduced the rolling resistance which has a positive effect
on the fuel consumption and the CO 2 emission. Furthermore,
the durability as well as the wet traction improved.
