1、Chemical Name: methacrylic
glyceride
2、Shortened Form: rubber cross-linking agent (alias:
homo-polyester 12-1)
3、Properties: The rubber cross-linking agent
is a new rubber assistant, pertaining to innocuous multi-function
additives. It performs in the rubber mixing as the plasticizing
agent, in the vulcanization as the cross-linking agent, and
when used in white rubber of inert filler, it can highly improve
the hardness, strength and elongation. Besides, it can enhance
the brute force and hardness of the rubber, improve the adhesion
strength with metal and chemical fiber textiles, and greatly
shorten the mixing time, thus improving productivity.
4.Application: It is mostly used in
acrylonitrile butadiene rubber, chloroprene rubber, ternary
ethylene propylene rubber, natural gum, butyronitrile, polyethylene,
sizing materials and so forth, and applicable to the making
of a variety of machines, dustproof and waterproof, uncured
testing tubes under oil wells. Besides, it is acceptable in
the fabrication and maintenance of miscellaneous tires, rubber
fittings, rubber rollers and other rubber products.

8、Storage and Prevention: Store in
dry, shady, ventilated storehouse, isolated from fire and
avoiding insolation. The storage life is six months. (Notice:
we are researching on innocuous light-colored rubber cross-linking
agent, mainly used in white, colored and medical rubbers.)

1、Appearance: light camel powder, sans
taste, and non-corrosive.
2、Properties: It performs as the
fluid rubber cross-linking agent. However, its usage is
more convenient.
3、Application: It is used the same
as the fluid rubber cross-linking agent, and is composed
of 65 percent of fluid rubber cross-linking agent, 25 percent
of white carbon black, and 10 percent of light calcium carbonate,
which can be set in terms of the requirement.
4、Packaging: 25kg net Wt, inside
plastic bags, packed by polyacrylic fiber-made knitting
bags outside.
5、Storage and Prevention: Store in
dry, moistureproof, ventilated, shady places. The storage
life is six months.
⊙ Methacrylic
magnesium
1、Chemical Name: methacrylic magnesium
2、Shortened Form: MMg
3、Structural Formula:
4、Properties:
As the bivalent metal-salt of the unsaturated organic acid,
it is used to vulcanize rubber, and produces saline cross
bond, performing very well due to its initiator-CDP. The
vulcanized rubber owns the characteristics of high strength
and elongation, resistance to high/low temperatures, especially
of high hardness, brute force, resistance to tearing and,
the high bonding nature and fatigue durability. Besides,
It can decrease the permanent deformation of the intense
light sizing materials of white carbon black, with special
properties as temperature durability, oil resistivity, and
high-voltage durability.
5、Application: It is used to manufacture
high-strength unfilled sizing materials and high-hardness
ones and applicable to a variety of high pressure seal components,
miscellaneous mechanical dustproof or waterproof rings,
as well as to the making of airtight products with high
oil resistivity, high temperature durability, and frost
resistance.

plastic bags, packed by polyacrylic fiber-made knitting
bags outside, with tightened necks.
9、Storage and Prevention: Store in
the temperature below 30 degrees centigrade, far away from
heat and fire sources, and in the waterproof and moistureproof
places, above 0.5 m from the ground. (Notice: We are researching
on a series of products like methacrylic calcium and methacrylic
zincum.)
⊙ NAPM
1、Chemical Name: N- (4- aniline phenyl) methacrylic amide
2、Structural Formula:
3、Properties: The product is one of the polymeric rubber
anti-aging agents, and it can copolymerise with butadiene
and Acrylon to get acrylonitrile butadiene rubber, which
is durable to high temperatures and media, thus, spanning
the storage and application life of the rubber products.
4、Application: It is mostly used as the anti-aging agent
in the copolymerisation between raw rubber and rubber monomer,
and owns the function of anti-aging and polymerization.
5、Technical Index: Appearance: bice, powder. Melting Point:
100-104 degrees centigrade
6、 Packaging: 25 kg net Wt, inside plastic bags, packed
by polyacrylic fiber-made knitting bags.
7、Storage and Transportation: Store in dry, moistureproof,
ventilated, shady places, above 0.5 m from the ground; tighten
necks in transportation and avoid inverting; store it away
from water and fire.
⊙ Methacrylic
zincum
As the rubber vulcanized assistant and heat resisting additive,
the product is durable to acid, alkali, corrosion, and high
temperature. Combined with rubber, it forms saline cross bonds,
which can improve the strength of the vulcanized rubber and
better the high-low temperature. Besides, it can increase
elastane and resistance to tearing, reduce white carbon black,
and decrease the compression permanent change of reinforcement
sizing materials.
Although methacrylic zincum and methacrylic magnesium
(currently used) belong to the same series of products,
methacrylic zincum looks loose, tenuously granular. The
even spread in use can improve operating efficiency, in
addition to its preceding methacrylic magnesium in increasing
the flexibility and strength of rubber.
