Would this be suitable to use inside a projector?

In principle, the filter works very well with a projector. However, the temperature should be noted. The filter can withstand a maximum of 80 ° / C. However, I cannot know exactly which filter was installed in your projector.

Would this be suitable to reduce glare from a smart phone mounted on the handlebars of a bike?

Unfortunately, this is not an application for this filter.

Do you have the same specs self-adhesive filter but for circular (not linear) polarisation?

Yes, please look for type ST-37. But only none adhesive.

Will this work on a garmen gps map 178c. Is this self adhesive?

Type ST-38-20 is non-adhesive and Type ST-38-20S is single-sided self-adhesive. The polarization axis must be found by turning the filter.
