Industry: Chemicals

Press Release Summary: Thankyou Chem (Henan) Co.,Ltd.,owning shares of two chemical
plants,one marketing company,one technology and products research center, is a
professional chemical producer and exporter in China. The main business is the
chemical products, especially it is continuo-usly making the remarkable effort in
the resin profession.



Press Release Body: Petroleum resins is a kind of thermal plasticizing resin
produced by C5,C9 fraction, by products of petroleum cracking,through
pretreatment,polymerization and distillation.It isn\'t a high polymer but a low
plomer with the molecular weight between 300-3000.Featured by acid value,easy mutual
solubilities, resistant to water,resistant to ethanol and chemicalls,it has the
chemical stabilizing property to acid and alkaline,viscosity adjusting and thermal
stabilizing ,Gernerally,the petroleum resins are not used independently,but have to
be used together with other kinds of resins as promoters,adjusting agents and
modifiers.

Properties and functions of petroleum resins in diffent fields.

A.Paints
Paints mainly use petroleum resins, DCPD resins and C5/C9 copolymerized resins with
high softening points,petroleum resins . Petroleum resins can increase the final
finishes of paints,the adhesiveness. Of paints films and the hardness,resistane to
acid alkaline.
B.Rubbers
C5 petroleum resins,C5/C9 copolymerized resins and DCPD resins with low softening
points are mainly used with rubbers which kinds have good mutual solubilities with
rubber particles, no influence on the sulferization of rubber.Rubbers added with
petroleum resins will increase the strenth, adhesioveness and softening characters.
C.Adhesives
Petroleum resins itself have very good adhesiveness,they can strenthen the
adhesiveness of adhesives,resistance to acid, alkaline and water, they will reduce
the production cost.
D.Printing inks.
Usually, the C9 petroleum resins and DCPD petroleum resins which have high softening
points are used for printing inks, they have color- spreading ,fast-dry and
brightening effects and will increase the printing property.
E.Others
Petroleum resins have a cetain unsaturation property and can be used as paper
glutting agents, plastic modifiers etc.


The testing method of petroleum resins:

Softening point: GB2294 coal asphalt softening point determination method.

Color: GB12007.1 color method (toluene:resin=1:1)
Acid value:GB2895 unsaturated polyester resin determination method.

Br. value( iodine value): indicator titration method.

Ash content：GB coal asphalt ash content determination method .


Packing, storage and defence:

Packed in 25kgs paper bag, pp bag or paper and pp compounding bags; it should be
stored in dry place with fire fighting facilities.Far away from fire, moist and
pollution.
