| High
Quality Protector |
Quality Protect Film was developed
in 1961, for protecting car bumpers
from scratches.
Since then, Nitto Denko has continued
to develop new surface protection products
in response to various customer needs,
in support of the diversification and
development of industry.
These tapes, created by combining special
films and adhesives, utilize Nitto Denko's
advanced synthesis and adhesive technologies.
Based on film materials such as polyvinyl
chloride (PVC), polyolefin (PO), and
polyester (PET), with rubber or acrylic
adhesives, by incorporating Nitto Denko's
original polymer synthesis and coding
technologies, 150 products have already
been brought to market. From surface
protection products for sheet metal
such as stainless steel, aluminum, and
pre-coated steel plate, to component
materials for housing and preservative
materials for automobiles, and now to
electronic & optical industries,
their fields of application are expanding.
Nitto Denko continues to meet the challenging
demand for higher performance and diversity
in all aspects of society, while working
to create further added value in the
form of reliability.

| How
to Select
To select the most suitable surface protection
material
Nitto Denko has a wide variety of
surface protection materials that
meet your needs and demands. To select
the surface protection material most
suitable for the application and environment
it is going to be used, detailed information
corresponding to a particular function
is required. Please refer to the "Basic
functional requirements for surface
protection films" and "Criteria
for selecting a surface protection
product" below when selecting.
With the information you get from
these charts, please consult our staff
at the nearest sales office for additional
assistance and information.
Basic funciional requirements
for surface protection films
|
Function |
Key point |
|
Lamination |
In
any climate, the ability to
laminate smoothly without wrinkles
or air bubbles (low temperature
dependency of base and adhesive)
High-speed
lamination capability |
|
Processing |
No
lifting or breaks from light
processing such as cutting,
piercing or bending, or from
heavy processing such as spinning
or roll-forming
Sufficient
adhesive strength for the surface
protection
Film
and adhesive are not affected
by press oil, paint or chemicals |
|
Storage |
Heat,
pressure, ultraviolet rays,
etc. do not result in film deterioration
or changes to the protected
surface. (No contamination or
adhesive residue) |
|
Peel |
Film
peels readily, in any climate |
Criteria
for selecting a surface protection
product
Test Methods
To provide better products
To ensure product precision and reliability,
Nitto Denko's SPV products are all
subjected to rigorous testing that
complies with Japan Industrial Standards
(JIS).
JIS Z 0237:2000
Method of testing adhesive tape and
adhesive sheet (itemized)
| Adhesive strength |
|
Condition
Adhesive strength of specimen
peeled at 180 and 90 degrees
to the test plate.
1.Leave a test plate with the
test specimen adhered thereto
stationary for not less than
five minutes in an atmosphere
at a temperature of 23+/-2 °C
and a relative humidity of (50+/-5)%.
2.Clamp the free end of the
specimen is clamped in the upper
chuck. Be careful to ensure
the folded-over part of the
specimen is being parallel to
the adhered surface.
3.Peel the specimen continuously
at 300+/-30 mm/min and measure
it at four points with 20 mm
intervals. |

| Test
method |
|
1. |
Set
the distance at 100mm between
the grippers of the tensile
test machine and between gage
marks on test specimens. |
|
2. |
Stretch
specimens at 300+/-30mm/min. |
|
3. |
Measure
the load and elongation up to
the point at which the specimen
is being failed. Fabricate another
specimen and perform the test
again, if the specimen fails
at a gripper portion.
