What is a Tenac?
TENAC™ is the trademark of polyacetal resin manufactured and sold by Asahi Kasei. TENAC™ is our polyacetal resin that was named after “TENAX” meaning “tough” in Latin.
Is acetal a plastic resin?
Acetal Resin
Polyoxymethylene, better known as acetal plastic, is a thermoplastic that has high stiffness, excellent dimensional stability, high flow, and low coefficient of friction.
What is acetal copolymer plastic?
Acetal is the common name for a family of thermoplastics with the chemical name “PolyOxy-Methylene.” Acetal is available in a general purpose copolymer grade, a homopolymer version Delrin®, and several filled Delrin® grades. Acetal provides high strength, stiffness enhanced dimensional stability and is easy to machine.
What is the difference between acetal and POM?
POM material, commonly called acetal (chemically known as Polyoxymethylene) is manufactured by Ensinger in standard stock shapes for machining and is extruded in sheet, rod and tube. POM plastic is a semi crystalline thermoplastic with high mechanical strength and rigidity.
Are Tenaculums still used?
The tenaculum is not the only obsolete toll still in use. Another commonly used device is the speculum. Specialists use the speculum- a two-bladed instrument that looks like a duck bill—to inspect the cervix, test for Sexually Transmitted Diseases (STDs), and obtain pap smears.
What are Tenaculums used for?
In most procedures involving uterine instrumentation, a tenaculum is used for stabilization and traction of the cervix and to decrease the flexion of the uterus to ease passage of instruments into the endometrial cavity.
What kind of plastic is acetal?
thermoplastic
Acetal plastic, also called polyacetal and polyoxymethylene (POM), is a general purpose, semi-crystalline, engineered thermoplastic. Acetal is commonly used for parts that need to be very stiff, have low surface friction and good dimensional stability.
Is acetal plastic toxic?
HAZARD SUMMARY
* Acetal can affect you when breathed in. * Contact can irritate the skin and eyes. * Breathing Acetal can irritate the nose and throat. * High or repeated exposure to Acetal can cause headache, dizziness and drowsiness.
What is acetal plastic used for?
Acetal plastic is commonly used as an alternative to metals, thus it finds applications in mechanical gears, electrical components, automotive products, sports equipment, medical products, food equipment, hardware, construction tools, and much more.
How can you tell if plastic is acetal?
Metal detectable acetals are manufactured by adding a metal detectable additive. If a plastic fragment were to break off during production, it can now easily be identified using a metal detector during production.
Is acetal same as Delrin?
Delrin® is an acetal homopolymer and has a uniform backbone with a larger crystalline block structure than acetal copolymers providing better chemical bonding. As a result, Delrin® is the stiffest and strongest unreinforced technical engineering polymer available.
Does a tenaculum puncture?
The vulsellum atraumatic tenaculum (also known as a Teale or Bierer tenaculum) has multiple small teeth that are not intended to puncture the cervical mucosa. It is similar to an Allis clamp but longer and angled in order to be used vaginally.
Does tenaculum pierce the cervix?
The tenaculum is an effective tool in engaging the cervix by using two sharp, pointed opposing points that pierce through the tissue of the cervix. However, the device can be painful for some patients and alternatives are limited.
Are Tenaculums always used?
Tenaculum. The authors advise that a tenaculum should always be applied to stabilise the cervix and to reduce the risk of uterine perforation by gently straightening the cervico-uterine angle.
Is Acetal a carcinogen?
Cancer Hazard
* Cancers of the nose and mouth were found in Acetal production workers who were also exposed to other known carcinogenic Aldehydes. The contribution of Acetal to the development of these cancers has not been determined. * Many scientists believe there is no safe level of exposure to a carcinogen.
What is Acetal plastic used for?
Is acetal a hard plastic?
High strength, stiff, low friction engineering plastic with good wear properties. Acetal (polyoxymethylene or POM) is a high strength, low friction engineering plastic that has excellent wear properties in both wet and dry environments. Acetal is chemically resistant to hydrocarbons, solvents, and neutral chemicals.
Does a tenaculum damage the cervix?
These are arranged in order of frequency. Laceration of the cervix. As a result of resistance to dilation at the internal os, the tenaculum holding the cervix may tear through and cause bleeding.
How painful is the tenaculum?
The tenaculum is a medical instrument that has been commonly used in gynecology for over a century. Every year, about 80 million women around the world suffer from trauma caused by the use of this device. In fact, 89% of women report moderately to severe pain during procedures using tenaculum.
Why are tenaculum still used?
Is acetal biodegradable?
Acetal-Derivatized Dextran: An Acid-Responsive Biodegradable Material for Therapeutic Applications.
Why are Tenaculums still used?
Can you insert IUD without tenaculum?
Carevix is a soft-suction cervical device designed as a more modern and gentler alternative to a tenaculum to stabilize the cervix for the insertion of an IUD for contraception. By using suction technology, the device delivers cervical engagement without the need to perforate the tissue.
Does the tenaculum puncture the cervix?
COMMENTARY. The vulsellum atraumatic tenaculum (also known as a Teale or Bierer tenaculum) has multiple small teeth that are not intended to puncture the cervical mucosa. It is similar to an Allis clamp but longer and angled in order to be used vaginally.
Can acetal be recycled?
Acetal is 100% recyclable. See our blog on recycling engineered plastic waste for more information on the process.
