[About SDS request]

　Regarding requests for SDS submission, we basically do not support SDS for molded products.Some domestically procured chemical products may be submitted for raw materials before molding, so please contact us if you wish.
Regarding metal molded products, except for painted products (paint part), we do not contain SDS, but contain harmful substances based on the requirements such as ROHS2 Directive and EN71-3, which are generally applied as safety indicators for metal miscellaneous goods. It is possible to submit survey materials for the amount (or elution amount).
SDS is originally a document for dangerous and harmful chemicals, and is treated as follows by the three laws (Chemical Control Law, Safety and Deleterious Substances Law) that require the provision of SDS in Japan. I am.

● Chemical Substance Method (Chemical Substance Emission Control Promotion Law): “Solid substances” are included in products that do not need to be provided with SDS. "Solid matter (a product that does not become non-solid and does not become powdery or granular in the process of handling by the business operator)"

● Industrial Safety and Health Act: Products that do not need to be provided by SDS include the following. "Products that do not become non-solid and do not become powdery or granular during the handling process by workers"

● Poisonous and Deleterious Substances Control Law: There are some "forms" containing the relevant substances that fall under the category of poisonous / deleterious substances, but "the ones that can be grasped by the concept of instruments, equipment, and tools" are not considered to be "forms".

List of compliance with RoHS/CPSC/EN71 regulations (heavy metals including lead) by material

Note) Click the blue letters in the table to see the details.

*1:
In the analysis of EN71 Part3, it is the result of the elution inspection of the plated products.
(Please note that it is not a cloth)
In other words, it was found that even products that contain a lot of lead can meet the EN71 Part 3 standard, which is assumed to be swallowed, even for products that are plated on the surface, which are normally sold in the market.

*2:
CPSC's CPSIA (Consumer Product Safety Improvement Act) regulates lead content for children under 12 years of age.
Paint and surface coating90ppm or less
Other than paint and surface coating100ppm or less

List of compliance with RoHS/CPSC/EN71 regulations (heavy metals including lead) by product

Note) Click the blue letters in the table to see the details.
The unit of the numbers in the table is ppm (1000ppm=0.1%)
"ND" in the table indicates less than the lower limit of quantitative measurement
"---" in the table indicates that it is not subject to inspection (since metals theoretically do not include PBBs and PBDEs)

*1:
In the analysis of EN71 Part3, it is the result of conducting a lead elution test for products with plating.
(Please note that it is not all 8 elements and it is not the fabric)
In other words, it was found that even products that contain a lot of lead can meet the EN71 Part 3 standard, which is assumed to be swallowed, even for products that are plated on the surface, which are normally sold in the market.

Trends found from a series of analysis results

We will publish the analysis results of heavy metals including lead in rubber cast products.
Rubber casting is a method in which a lead alloy of tin is melted, poured into a rubber mold that rotates at high speed, and centrifugally cast.
Since it uses rubber, it is an alloy that can be handled at low temperature at low cost and has been widely used since ancient times.
However, since the raw material is an alloy of tin and lead, the corresponding raw material contains lead.
In the accessories and metal miscellaneous goods industry, even the same alloys are roughly classified into two according to their mixing ratio and used properly.

High meta:

High tin content and low lead content
It is light and durable, and it is easy to express detailed details, but the unit price is high

Low meta:

Low tin content and high lead content
It is heavy and fragile, and it can not produce detailed details, but the unit price is cheap

From the above characteristics, low metal tends to be used for inexpensive metal miscellaneous goods and high metal for expensive accessories.
We have received an analysis table of the raw materials currently used from our cooperating factories.
　<Cast metal analysis table>

Even high-metal contains 5% lead, and low-metal contains more than 50% lead.Do not let infants lick, put in mouth, swallow, etc.Adults should handle with care.

Used by us　Rubber cast product example

Normally, it is not sold in the form of cloth, and since the surface is plated (nickel plating, etc.), it is unlikely that it will come into direct contact with lead. It seems that you need to be careful.

Among the sawed parts used in our company, about the mobile strap parts (pine needles) that we surveyed this time, improve the machinability to brass (brass: alloy of copper and zinc) that is the raw material of the metal part (saved parts) Therefore, it was found that the lead contained 1.869%.

Mobile phone strap parts　<Analysis result 1>　<Analysis result 2>　<Analysis result 3>

Since the surface is plated (nickel plating or gold plating), it is unlikely that it will come into direct contact with lead.Do not let infants lick, put in mouth, swallow, etc.Adults should be careful in handling.

　Cooperating factory A<Component analysis table>
　Cooperating factory B<Component analysis table>
　Cooperating factory C<Component analysis table>

The amount of lead contained in the materials used in the product is extremely small and is within a range that does not pose a problem.
Zinc die casting is a method in which a zinc alloy is melted and poured into a mold at high pressure for casting.
Zinc alloy is an alloy whose main raw material is zinc, and casting means casting.
