Heat curing types of silicone and fluorosilicone rubber are discussed, including the very latest types of liquid silicone
rubbers designed for moulding and coating (e.g. wire and fabric) processes. The trend of the industry towards supply-
ing silicone rubber in base form is described together with a number of new additives which improve the processing
and/or vulcanisate properties.
The developments in processing of silicone and fluorosilicone rubber indicate the enormous improvements made since
the early materials were introduced and how even nonmilling, ready-to-use, silicone rubber has been developed by
controlling the filler/polymer interaction.
A very high proportion of the usage of silicone rubbers is associated with electrical applications, particularly wire and
cable for the electrodomestic appliance and automotive industries. The inherent properties of silicone rubber make it
a natural choice in areas such as safety (flame retardant) cables and food contact applications. Examples ofthe latter
uses are given. In addition reference is made to automotive hose, electrically conductive applications, dynamic seals
and medical implants.
The trend towards the use of silicone rubber in consumer products (cars, domestic appliances, etc.) seems certain to
expand its use. This has been made possible by the unique propertiesof silicone rubber combined with a new commercial
and technical flexibility for the fabricatorof finished parts.
Silicone tube is a type of silicone rubber and belongs to single-component room temperature vulcanized liquid
Silicone products are a kind of silicone rubber products and belong to one-component room temperature vulca-
nized liquid rubber products. Once exposed to the air, the silane monomer therein undergoes condensation,
forming a network structure, the system crosslinks, does not melt and dissolve, has elasticity,becomes rubbery,
and adheres to the object.
Its thermal conductivity is slightly higher than that of general rubber products. Once cured, it is difficult to separate
bonded objects. Rubber products are highly elastic polymer compounds. Includes uncured and already vulcanized
varieties. Can be divided into two major categories of natural rubber and synthetic rubber. Natural rubber products
are processed from rubber latex obtained from plants.
Synthetic rubber products are obtained by polymerizing or polycondensing monomers. Unvulcanized rubber products
are commonly called raw rubber products or raw rubber. Vulcanized rubber products are called vulcanized rubber
products, commonly known as cooked rubber products or rubber. Widely used in the manufacture of tires, hoses, tapes,
insulation materials, rubber shoes, silicone tube in medical applications. Silicone products swimming caps are mainly
made of high-grade silica gel products. The silicone tube feels softer, has stronger stretching force, and is very durable.

Clamp is mainly used in automobiles, tractors, ships, gasoline engine, diesel engine, sprinkler and other kinds
of mechanical equipment on the oil, gas, hydraulic hose joints.It is necessary for all kinds of rubber hose interface
fastening connection accessories, as well as building sewer interface, etc.

Aluminum tubes are mainly divided into the following types According to the appearance of points: square tube,
round tube, pattern tube, shaped tube, global aluminum tube.
According to the extrusion method: seamless aluminum tube and ordinary extruded tube.
According to precision points: ordinary aluminum tubes and precision aluminum tubes, precision aluminum tubes
in general need to be re-processed after extrusion, such as cold-drawn fine pumping, rolling.
According to thickness: ordinary aluminum tube and thin-walled aluminum tube Performance: corrosion resistance,
Aluminum tube advantages: First, the welding technology advantages: suitable for industrial production of thin-walled
copper-aluminum pipe welding technology, known as the world-class problem, is the key technology of air-conditioning
connection tube aluminum substitute copper.
The second is the advantage of service life: From the perspective of the inner wall of the aluminum tube, since the refri-
gerant does not contain moisture, the corrosion of the inner wall of the copper-aluminum connection tube will not occur.
The third is the advantage of energy conservation: the connection between the indoor unit and the outdoor unit of the air
conditioner. The lower the heat transfer efficiency, the more energy-efficient, or, the better the insulation effect, the more
Fourth, excellent bending performance, easy installation and transfer.
The demand for silicone tube market continues to expand, and the silicone product factory is constantly emerging.
To be based on the current material level, it is not only to ensure the quality of the product in the silicone industry.
Silicone manufacturers must shorten the cost, reduce the cost and then improve the production efficiency. Live the
heel. So how to increase production capacity and reduce production costs without affecting product quality? First
of all, the extruded silicone tube must undergo the stage of vulcanization in the production process. Generally, if the
vulcanization temperature is relatively low, the performance of the product will be better, but the production capacity
will decrease and the cost will increase. In this case, we can increase the amount of vulcanizing agent to achieve
rapid vulcanization, shorten molding time and increase production efficiency. This is the easiest method. Secondly, it
is also possible to get the operator up and down, let the skilled personnel try to speed up the operation, reduce the
time outside the mold, stabilize the mold temperature, and increase the vulcanization speed. In addition, we can also
change the way of raw material discharge, change the number of exhaust and exhaust stroke, etc., but these are
determined according to the different structure of the product, not all products change the exhaust times and exhaust
strokes are the same .
