Plastic PVC ASA Roofing Sheet Knowledge
Recently, this artifical glazed plastic roof tile product becomes
more and more popular worldwide, especially in Asia and South
America,
due to its features of bamboo shape and long lifespan.
The secret of the plastic roof tile features lie in the surface
layer which is made of ASA or PMMA granule. The greatest benifit of
ASA or PMMA is the ability to resist ultroviolet when placed on top
of house, in this way the appearance of the plastic roof tile can
keep fresh for more than 25 years.
The plastic roof tile products will not cause any problem for the
environment, instead through a series of plastic sheet recycling
machine which we also called plastic auxiliary machine such as
plastic sheet crusher and miller, it can be recycled when damaged
or wasted during the roof tile production, and it can be resued to
feed the production line again as the middle layer to save the
cost.Meantime, the filler material used in plastic rooding products
is calcium carbonate which is very cheap and costs USD100 per ton.
PVC ASA Plastic Roof Tile Extrusion Line
Acemien plastic roofing tile making machine integrated the most
reliable co-extrusion and control technology to produce strong and
long lifespan plastic roof tile with customized surface printing
pattern, and the tile forming mould block is smoothly polished and
fixed properly.
1,Materials compounding
Using our high efficient reliable vertical raw material mixer, the
raw materials such as PVC powder,Calcium Carbonate, and other
additives likecloride PE, pre-wax, stearic acid, compound
stabilizer, ACR, Paraffin are mixed together and homogenized, which
is very important in sheet making, because the improper mixing
would lead to product deficiency problem like crack, bubble and
bump.
2,Co-extrusion
In this stage, the completely mixed raw materials are transported,
molten and fully plasticized, and then transferred to the sheet die
mould due to extruder pressure caued by rotating screw, where the
sheet thickness can be adjusted between 1mm to 3mm through screw of
mould lips, finally the ASA coating layer is formed on the surface
of roof tile.
3,Forming and cutting
In the final stage, the hot PVC ASA sheet is tracted to the tile
forming machine with glazed mould after trimming, in which the wind
generated by the cooling fan at both side will blown into a tunnel
to cool down the temperature for the glazed mould after absorbing
the heat from the running hot roof tile sheet, and then the formed
glazed PVC tile sheet continues to be tractedto a cutting machine,
where a certain length of the glazed roof sheet is cut as per PLC
programmed, and finally the glazed roof sheet are piled on the
stacker table which is ready to be packed.

PVC ASA roof tile advantage
1,Elegant and smooth shaping the of tile
2,Surface color last almost fresh by 25 year.
3,Anti-corrusion,will not rust like the iron or metal tile.
4,Heat resistant due to low conductivity of the roof sheet.
5,Used As durable weather sheet, and also for counterpart of wall
panel sometimes.
6,Noise proof when it rains and winds.
7,Heavy load bearing even to heavy snow,rain and falling objects,
strong enough to hold against Typhoon.
8,Self cleaning when it rains due to special surface embossing
pattern.
9,Easy to install and transport.
10,Environment friendly, can be recycled by plastic crusher and
miller to be reused to extrude middle layer ,then to reduce
manufacturing cost.
11,Anti Ultraviolet.
