Trelleborg Sealing Solutions launched FoodPro E75F1, an elastomer sealing material.Get more news about Plast Recycling Maskine,you can vist our website!

FoodPro E75F1 is a shore EPDM universal sealing material for static and semi-dynamic food applications, such as separators, decanters, valves, pipe couplings and heat exchangers, in any type of seal design, from standard O-rings and gaskets to multicomponent parts. It combines with other rubber, plastic and metal materials, allowing for the creation of multicomponent products, which helps eliminate potential dead space where bacteria may grow, according to the company.
The material is compression and injection moldable into complex geometries and withstands surface imperfections in applications. It was developed specifically for use in high-temperature dairy processing, including infant formula, and complies with all major global food contact regulations.

"Processing equipment manufacturers can look to FoodPro E75F1 to meet their customers' needs because of its suitability for the widest range of applications," said Mikkel Moerup, global segment director of food and beverage at Trelleborg Sealing Solutions. "They no longer need to specify sealing materials for each piece of equipment dependent on geographical use, process media and cleaning regimes."
Objective: The aim is to determine the perception of pain and discomfort by the patient during the placement of orthodontic separators. Methods: Elastomeric separators were placed mesially and distally to the first molars in 200 orthodontic patients, and the participants were given self administrated questionnaires to document perceived pain, type of pain felt, pain upon chewing, and the severity of pain's affecting daily life, using a visual analog scale for three days. Results: The mean perceived pain scores out of 100 on the first 3 days were:49.00±27.7 88.00±30.7 and 25.12±14.3 respectively; chewing pain scores were: 49.25± 33.49 ,78.80 ± 44.2, 31.21± 20.01,respectively; the pain's affecting daily life scores were16.7 ± 26.7,28.1± 38.7, 14.6±12.1, respectively. A Kruskal-Wallis test showed a statistically significant difference in the reported pain between the studied parameters. Conclusion: 51.7% of population reported pain after separator placement.88% of patients reported the maximum intensity of pain one day after separator placement. Intensity of pain reduced two days after separator placement.56.12% of patients had to change their food consistency.

Elastomeric separators can be difficult to place when a posterior tooth is partially erupted, submerged, or trapped under the adjacent tooth. In addition, many adult patients present with extremely worn occlusal surfaces and tight contacts. Although wire separating springs have traditionally been used in such situations, a better alternative is to fabricate a separator from elastomeric thread.Get more news about Plast Recycling Maskine,you can vist our website!

We use Ultra Tuff .030" elastomeric thread, which has a textured surface to keep it from coming untied. A strand of dental floss is first placed between the contacts, then doubled over to form a loop (Fig. A). The elastomeric thread is pulled through to the buccal surface with the loop (Fig. B). One end of the thread is then pulled free, and the floss is removed. The thread is tied three or four times (Fig. C), reversing the direction each time to prevent slippage, and cut off (Fig. D). In some cases, it may be possible to insert the thread directly into the contact without the floss loop.

After one or two weeks, the thread is removed by grasping the knot with an instrument (Fig. E). This technique usually creates sufficient space to place an elastomeric separator. It also allows trapped molars to erupt and upright, saving treatment time (Fig. F). It provides better separation and is more comfortable than separating springs.

The vast majority of plastic that people use, and in many cases put into blue recycling bins, is headed to landfills, or worse, according to a report from Greenpeace on the state of plastic recycling in the U.S.Get more news about Plast Recycling Maskine,you can vist our website!

The report cites separate data published this May which revealed that the amount of plastic actually turned into new things has fallen to new lows of around 5%. That number is expected to drop further as more plastic is produced.

Greenpeace found that no plastic - not even soda bottles, one of the most prolific items thrown into recycling bins - meets the threshold to be called "recyclable" according to standards set by the Ellen MacArthur Foundation New Plastic Economy Initiative. Plastic must have a recycling rate of 30% to reach that standard; no plastic has ever been recycled and reused close to that rate.

"More plastic is being produced, and an even smaller percentage of it is being recycled," says Lisa Ramsden, senior plastic campaigner for Greenpeace USA. "The crisis just gets worse and worse, and without drastic change will continue to worsen as the industry plans to triple plastic production by 2050."Waste management experts say the problem with plastic is that it is expensive to collect and sort. There are now thousands of different types of plastic, and none of them can be melted down together. Plastic also degrades after one or two uses. Greenpeace found the more plastic is reused the more toxic it becomes.

New plastic, on the other hand, is cheap and easy to produce. The result is that plastic trash has few markets - a reality the public has not wanted to hear.

Trent Carpenter, the general manager of Southern Oregon Sanitation, says when they told customers a couple years ago that they could no longer take any plastic trash other than soda bottles and jugs - like milk containers and detergent bottles - people were upset. They wanted to put their strawberry containers, bags, yogurt cups and all manner of plastic trash in their recycling bin.

"We had to re-educate individuals that a great deal of that material is ending up in a landfill," Carpenter said. "It's not going to a recycling facility and being recycled. It's going to a recycling facility and being landfilled someplace else because [you] can't do anything with that material."

That message has been difficult for the public to absorb with so many different bins in public spaces, and their own communities telling them to put their plastic in recycling containers.Carpenter says they wanted to be transparent with their customers and tell them the truth, unlike companies that continue to tell customers that plastic, such as bags and containers, is being turned into new things.

"Politically it's easier to just say 'Gosh, we're going to take everything and we think we can get it recycled,' and then look the other way," Carpenter said of the other companies. "That's greenwashing at its best."

Greenpeace found a couple facilities are trying to reprocess cups and containers - sometimes called "number 5s" because of the markings on the containers. But the numbers are low. While 52% of recycling facilities in the U.S. accept that kind of plastic, the report found less than 5% of it is actually repurposed - and the rest is put into a landfill.
