This is among our most common concerns asked by our new and long-term customers, and is a little bit challenging to respond to. All Delrin is Acetal (POM), however not all Acetal is Delrin. (All Fords are cars and trucks, not all cars are Fords)

Several makers generate Acetal material, including: Celanese, BASF, Ticona, Sabic as well as many more.The homo-polymer Acetal material generated by Dupont as well as is called Delrin. The generic Acetal covers both the homo-polymer as well as the co-polymer grades of material. Both products meet the standard arrangements of the ASTM-D-4181 spec. Homo-polymer is noted under POM 111, and Co-polymer is POM 211. each square inch -levels F 257 220

Several of our most prominent concerns are "Is this product UV steady?", or "How much time will this last in direct sunlight?", or some comparable themed concern. These are wonderful concerns. Simply take a look at the 'inexpensive' yard furnishings you purchased last period, yep, it is discolored as well as cracking or damaged. Why is that?The fast
answer is the material had either no UV (Ultra Violet Light) stabilizer or little - or it was simply the wrong plastic for the component. Many plastic materials are not UV stable to begin with, other than Polymer which is undetectable to UV. All other products need a little something (an additive) to offer it the defense it could need from the sun. Several plastic materials, if provided the correct UV resistant ingredients, could be utilized in direct sunshine for 10 - 15 years, or a lot more, providing superb performance in severe environments.Additionally, many materials will certainly function well if they are painted to cover the plastic surface. Several spray paints, particularly Acrylic paints, last several years in the sunlight. Please consult us, as some material do not accept paints or coatings.Take time to assess your demands, and also the homes of the plastic you
plan to utilize. The right material will certainly provide the finest efficiency.
