ETHAFOAM* Brand Polyethylene Foam, M* Series
DESCRIPTION
In its second year of production and newly renamed, the original
family of products. ETHAFOAM M1, ETHAFOAM M3, ETHAFOAM M4, and ETHAFOAM
M5 (for "Grade A" applications) has been expended to include ETHAFOAM
M1 AS and ETHAFOAM M3 AS (with integral anti-static agents for "Grade
B" uses). All are designed specifically to match the cushioning
and physical performance of traditional ETHAFOAM products and to
contain less than 10% of the Lower Explosive Limit (0.1 LEL) of
residual flammable gasses as specified for use in sealed cases.
ETHAFOAM M-Series Products can be used in the many different cushion
configurations of existing container designs without any expected
change in shock or vibration protection. In addition, design criteria
that have been developed over several decades, can be applied when
designing new systems for protection. In addition, design criteria
that have been developed over several decades can be applied when
designing new systems for protecting sensitive items during shipping
and storage.
PRODUCT FEATURES
ETHAFOAM M-Series Products are manufactured using a variation of
Dow's unique RapidRelease process technology and preserve the time-tested
overall performance of ETHAFOAM, the industry standard upon which
the current Federal Specification PPP-C-1752 D was founded. Meeting
the ETHAFOAM Standard means that these products can be relied on
to satisfy the exacting military demands for long-term protection
in military containers - even in ways not measured by the formal
specifications.
The "M-Series" Products maintain features like resiliency, durability,
light-weight, and resistance to creep under constant load, which
have attracted military package designers to ETHAFOAM over the years.
One of the most critical measures of performance is the ability
of the material to provide predictable dynamic cushioning over a
wide range of static loadings. Dynamic cushioning curves for "M-Series"
Products are available by contacting API at the number listed below.
Special formulations, employment of the RapidRelease process, and
use of a Dow-developed testing procedure combine to allow the lot-by-lot
certification that the cells of "M-Series" Products contain less
than 10% of the LEL of flammable gasses at the time of shipment.
Thus, with a rather conservative margin of safety, the foam cannot
create a flammable atmosphere in closed care applications.
AVAILABLE FROM API
A more subtle, but no less important, factor in foam performance
is the ease with which it can be fabricated into the myriad of cushion
shapes required. "M-Series" Products, which have the same physical
characteristics as traditional ETHAFOAM products, can be fabricated
by methods proven to produce finished parts that meet the military's
stringent standards of dimensional accuracy. Fabricated parts are
available through API. API employs an exclusive group of Professionals
trained to provide a full range of services such as assistance in
design, prototyping, estimating, and documentation to augment their
capabilities for on-time production and shipment of quality parts.
